A CBS News/New York Times poll found that 329 out of 763 randomly selected adults said they would travel to outer space in their lifetime, given the chance. Estimate the true proportion of adults who would like to travel to outer space with 88% accuracy. Round your answers to at least three decimal places.

Answers

The true proportion of adults is in the interval 0.4026< P< 0.4594.

Here we have to estimate the true population of adults who would like to travel to outer space with 88% accuracy.

Data provided:

selected (x) = 329

Total(n) = 763

Sample proportion (p') = x/n

                                       = 329/ 763

                                       = 0.431

Critical z-value = 1.59

margin of error(E) = z[tex]\sqrt{p'( 1-p')/n}[/tex]

                             = 1.59 [tex]\sqrt{0.431(1-0.431) / 763}[/tex]

                             = 1.59 × 0.0179

                             = 0.0284

88% confidence interval is:

(p' ± E) = ( 0.431 ± 0.0284)

          = 0.4594 and 0.4026

Therefore the estimate is 0.4026< P< 0.4594.

a bowling team has 6 members. how many ways can the captain of the team arrange the bowlers for a game

Answers

The number of ways in which captain of the team arrange the 6 bowlers for a game is 720.

Explain the term arrangement?Generally speaking, an arrangement among objects is just a collection of them. A combination (ordering is disregarded) or permutation is used to determine the number possible "arrangements" of the components (order is significant). An arrangement of items in a specific order is referred to as a permutation. Here, the components of sets were arranged in a linear or sequential order.

For the stated question-

Total members in bowling team = 6.

Number of ways to arrange them = 6!

Answers

It is concluded that the ratio of female and male viewers who enjoy the game shows the difference.

Explain the meaning of the term ratio of the number?When two or maybe more numbers are compared, the ratio shows how big one is in relation to the other. The dividend or quantity being divided is referred to as the antecedent, and also the divisor or quantity that also is dividing is referred to as the consequent. A ratio analyzes numbers by division.

According to the survey-

360 out of 500 females enjoy the game.

Thus,

Ratio female = number of females who enjoy/ total number of females.

Ratio female = 360/500

Ratio female = 0.72

Now, 600 out of 800 males enjoy a game show.

Ratio male = number of males who enjoy/ total number of males.

Ratio male = 600/800

The angles of a triangle add up to 180 degrees. The second angle is 6 degrees larger than the smallest angle. The third angle is 4 times as big as the smallest angle. Find the measure of the smallest angle (in degrees) degrees

Answers

The measure of the smallest angle A of the triangle is 29°, whose second angle is 6 degrees larger than the smallest angle and the third angle is 4 times as big as the smallest one.

we know that the Sum of the measure of all the angles in the triangle is 180 degrees.

Let,  ∠ A = smallest angle

  ∠ B = A+6

 ∠ C = 4 (∠A)

So, we can write that,

∠ A + ∠ B +  ∠ C = 180°

∠A + (∠A+6) + 4∠A = 180°

6 +  ∠A + ∠ A + 4∠A = 180°

6 + 6 ∠A = 180°

6∠A = 180° - 6

6 ∠A = 174

∠A = 174/6

∠A = 29°

Hence, the smallest angle A is 29°

What is an interaction?

In statistics, an interaction may appear when analyzing the relationship between three or more variables, and defines a situation in which the effect of one causal variable on an outcome forms on the state of a second causal variable.

Interactions are often considered in the context of regression analyses or factorial experiments. An interaction happens when an independent variable has a different effect on the outcome depending on the values of another independent variable.

To find an interaction, we need a factorial design, in which the two (or more) independent variables are crossed with one another, so there are reflections at every combination of levels of the two independent variables.

Answers

Answer:

The total profit for the grain merchant selling 600 quintals of rice is Rs 12800. To calculate this, we first need to calculate the profit on one quintal. The profit percentage is 7%, so if a quintal costs Rs 250 the profit is 7% of 250 which is Rs 17.5. Now we multiply this with the number of quintals sold, which is 600, to get Rs 10500 as the profit. We then add in the overhead charges of Rs 1000 to get a total profit of Rs 12800. The selling price of 600 quintals of rice is therefore Rs 12800 plus Rs 250 times 600, which equals Rs 180000.

Given that,

One day, a teacher of statistics randomly selected 10 pupils' names from a hat and instructed them to complete as many pushups as they could before class began. The 10 students who were chosen at random performed an average of 15 pushups, with a standard deviation of 9. Assume that the population's distribution of the maximum number of pushups is roughly normal.

We have to find what is the standard error of the mean.

We know that,

For this problem, we have the standard deviation for the sample, thus, the t-distribution is used.

The sample mean is of 15 is x=15 .

The sample standard deviation is of 9 is s=9.

The sample size is of 10 is n=10.

First, we find the number of degrees of freedom, which is the one less than the sample size, thus df = 9.

Then, looking at the t-table or using a calculator, we find the critical value for a 95% confidence interval, with 9 df, thus t = 2.2622

The margin of error is of:

M=ts/n

Then:

M=2.2622(9/√10)

M=6

The confidence interval is:

x±M

x-M=15-6=9

x+M=15+6=21

Which of the following is NOT considered one of the six basic facial expressions representing emotional states?a. Disgustb. Jealousyc. Surprised. Fear Help quick if you can! imagine there is a radioactive isotope that has a half-life of 500 years. a sample contains 50% parent and 50% progeny atoms. how old is this sample? for the given scenario, determine the type of error that was made, if any. (hint: begin by determining the null and alternative hypotheses.) an ice cream truck aims to keep 30 degrees as the mean temperature inside its delivery truck. one employee claims that the mean temperature inside its delivery truck is more than 30 degrees. the employee conducts a hypothesis test and rejects the null hypothesis. assume that in reality, the mean temperature inside its delivery truck is 32 degrees. was an error made? if so, what type? you are the system administrator for several windows servers in your company. instead of scheduling the same updates for all the windows servers, your systems engineer would like to begin approving the updates based on specific groups of servers. when 0.20 m nh4cl(aq) and 0.20 m naoh(aq) are mixed, the reaction represented by the equation above occurs and a strong smell of ammonia, nh3, is observed. based on this information, which of the following statements is true?
