The expected winning and the value of that prize, which gives an expected winning is c. $3.13 per ticket.

The expected winnings per ticket in the raffle can be calculated by adding the products of the probability of the expected value of winning each prize. The predicted wins per ticket may be computed as the total of each prize's value multiplied by its probability of winning, i.e.

Expected winnings per ticket

= (1/800) × $400 + (4/800) × $200 + (12/800) × $125 + (30/800) × $60 + (753/800) × $0

If we condense the equation, we obtain:

Calculating the total wins anticipated per ticket

= $0.50 + $1.00 + $1.88 + $0.75 + $0

Expected winnings per ticket = $3.13

Therefore, if you buy a ticket, the expected winnings per ticket are $3.13.

The value of the test statistic for the test of the manufacturer to test his bolts is -0.296.

Given that,

A manufacturer must test that his bolts are 4.00 cm long when they come off the assembly line.

So population mean, μ = 4 cm

Sample size, n = 49

Sample mean, x = 3.87 cm

Population standard deviation, σ = 0.44 cm

Level of significance, α = 0.02

Test statistic, z = (x - μ) / σ

Substituting,3

z = (3.87 - 4) / 0.44 = -0.296.

Hence the value of the test statistic for the test of the manufacturer to test his bolts is -0.296.

California college students who drink according to the centers for disease control and prevention, 60% of all american adults ages 18 to 24 currently drink alcohol. The proportion of drinkers in the population of CA college students is not 0.60.

We can infer the following from the provided information:

The proportion of college students in California who presently drink alcohol is the same as the proportion nationwide (p = 0.60), rejecting the null hypothesis (H0).

Alternative hypothesis (Ha): California college students are more likely to use alcohol than college students nationwide (p 0.60).

The population proportion is represented by the letter "p" in the hypotheses.

We need the sample size and the sample proportion to calculate the standard error and the z-score. According to the poll of 450 college students in California, 66% of them currently consume alcohol, yielding a sample proportion of 0.66.

SE = √(0.66*(1-0.66)/450) ≈ 0.023

z = (0.66 - 0.60) / 0.023 ≈ 2.61

By comparing the p-value to a preset significance level (such as 0.05), the conclusion is arrived at. We reject the null hypothesis if the p-value is less than the significance level. If not, we are unable to rule out the null hypothesis.

The appropriate inferences from the information are:

The percentage of drinkers among college students in California is not 0.60.

The percentage of drinkers in the adult American population (0.60) and the percentage of drinkers among college students in California differ statistically significantly.

Thus, this can be concluded regarding the given scenario.

The correct answer to your question is: the p-value of a significance test is the probability, assuming the null hypothesis is true, that the sample would produce a result at least as extreme (meaning, as far away from expected) as was actually observed.

This means that the p-value represents the strength of evidence against the null hypothesis, with lower values indicating stronger evidence against the null hypothesis. It is important to note that the p-value does not tell us the probability that the null hypothesis is true or false, but rather the likelihood of observing a result as extreme as the one observed in the sample data, assuming the null hypothesis is true.

There is approximately a 3.84% chance that a randomly selected adult has an IQ greater than 144.4.

To find the probability that a randomly selected adult has an IQ greater than 144.4, assuming their scores are normally distributed with a mean of 102.7 and a standard deviation of 23.5, we will use the z-score formula.

First, calculate the z-score:
z = (X - μ) / σ
where X is the IQ score (144.4), μ is the mean (102.7), and σ is the standard deviation (23.5).

z = (144.4 - 102.7) / 23.5
z ≈ 1.77

Now, use a z-table to find the probability corresponding to this z-score. The z-table value for a z-score of 1.77 is approximately 0.9616. Since we want the probability of an IQ greater than 144.4, we will find the area to the right of this z-score.

The length of side f is  8.38 in the triangle DEF.

In a triangle, the sum of the angles is always 180 degrees.

∠D + ∠E + ∠F = 180 degrees

∠D + ∠E + 166 degrees = 180 degrees

∠D + ∠E = 14 degrees

Now, we can use the Law of Cosines to find the length of side f:

f² = d² + e² - 2de cos(∠F)

f² = (5.2 inches)² + (6.8 inches)² - 2(5.2 inches)(6.8 inches) cos(166 degrees)

f² = 70.29 inches²

Taking the square root of both sides, we get:

This stage of group development is known as forming.

The group development process is a series of stages that a group goes through as they form, develop, and eventually come to an end. The first stage of this process is known as forming. During this stage, group members are getting to know each other and trying to establish common goals and a shared understanding of how the group will operate. They may be polite and reserved, as they are still trying to feel out the dynamics of the group.

Once the group has established its purpose and members have a sense of what is expected of them, they move into the norming stage. During this stage, group members begin to work together more closely and develop norms for behavior and communication. They may start to form stronger relationships with each other and trust begins to build.

The third stage of group development is storming. During this stage, conflicts may arise as group members struggle for power and influence. There may be disagreements about how the group should function or how tasks should be completed. However, if the group is able to work through these conflicts, they will move on to the next stage of development.

The final stage of group development is adjourning. During this stage, the group comes to an end. This may be due to the completion of a task or project, or it may be due to other reasons, such as members leaving the group or the group disbanding.

The alternative hypothesis would be: The proportion of people who own cats is smaller than 90%.

The null hypothesis for this test would be: The proportion of people who own cats is equal to or greater than 90%.

To conduct the hypothesis test, we would need to collect a random sample of 1400 individuals and determine how many of them own cats. Based on this information, we could calculate the sample proportion of cat owners and use this to test the claim that the population proportion is smaller than 90%.

We would use a one-tailed hypothesis test with a significance level of 0.005. If the p-value for our test is less than 0.005, we would reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that the proportion of people who own cats is smaller than 90%.
Hi! I'd be happy to help you with this question. You want to test the claim that the proportion of people who own cats is smaller than 90% at the 0.005 significance level.

To do this, we will set up our null and alternative hypotheses as follows:

Null Hypothesis (H0): The proportion of people who own cats is equal to 90% (p = 0.90)
Alternative Hypothesis (H1): The proportion of people who own cats is smaller than 90% (p < 0.90)

Here's a step-by-step explanation of how to test this claim:

1. Determine the sample size (n) and the number of cat owners in the sample (x): In this case, n = 1400, and x = 615.

2. Calculate the sample proportion (p-hat): p-hat = x/n = 615/1400 ≈ 0.439.

3. Determine the significance level (alpha): In this case, alpha = 0.005.

4. Calculate the standard error (SE) of the sample proportion: SE = sqrt[p*(1-p)/n] = sqrt[0.9*(1-0.9)/1400] ≈ 0.008.

5. Calculate the z-score: z = (p-hat - p)/SE = (0.439 - 0.9)/0.008 ≈ -57.63.

6. Find the critical z-value for a one-tailed test at the 0.005 significance level: z-critical = -2.576 (from a standard normal distribution table).

7. Compare the calculated z-score with the critical z-value: Since the calculated z-score (-57.63) is less than the critical z-value (-2.576), we reject the null hypothesis.

In conclusion, based on this analysis, we have enough evidence to support the alternative hypothesis that the proportion of people who own cats is smaller than 90% at the 0.005 significance level.

Answer: f(2) = -7   , g(3) = -29

Step-by-step explanation: this problem can be solved via substitution

-2(2) - 3 = -4 - 3 = -7

-3(3)^2 - 2 = -3(9) - 2 = -27 - 2 = -29

To solve this problem, we can use the formula for the future value of an annuity:

FV = PMT * ((1 + r)^n - 1) / r

where:

PMT = the monthly payment ($300)

r = the monthly interest rate (APR / 12 = 0.035 / 12 = 0.002917)

n = the number of months (18 years x 12 months/year = 216 months)

Plugging in the values, we get:

FV = 300 * ((1 + 0.002917)^216 - 1) / 0.002917

FV ≈ $77,300.31

Therefore, after 18 years of making monthly deposits of $300 into an investment plan with an APR of 3.5%, you will have approximately $77,300.31.

To compare this amount to the total deposits made over the time period, we can calculate the total deposits as:

Total deposits = PMT * n

Total deposits = $300 * 216

Total deposits = $64,800

We can see that the total deposits made over the 18-year period were $64,800, which is less than the final value of the investment of approximately $77,300. This is because of the effect of compound interest, where the interest earned on the investment is reinvested and earns additional interest over time, resulting in a higher final value.

The 90% confidence interval for the number of seeds in the fruit is (17.480, 19.920). To find the 90% confidence interval for the number of seeds in the fruit, we will follow these steps:

1. Identify the sample size (n), sample mean (x), and sample standard deviation (s): n = 70, x= 18.7, s = 6.2.

2. Since we want a 90% confidence interval, we will use a z-score of 1.645 (from a standard normal distribution table or calculator).

3. Calculate the standard error (SE) using the formula: SE = s/√n = 6.2/√70 = 0.741.

4. Calculate the margin of error (ME) using the formula: ME = z * SE = 1.645 * 0.741 =1.220.

5. Determine the confidence interval by adding and subtracting the margin of error from the sample mean: (x - ME, x+ ME) = (18.7 - 1.220, 18.7 + 1.220) = (17.480, 19.920).

Therefore, the 90% confidence interval for the number of seeds in the fruit is (17.480, 19.920).
