We are formulating a 95% confidence interval for the population proportion. We have taken a random sample of 100 observations and observed 10 instances of the characteristic in question. What would be the lower interval limit for our 95% confidence interval? (NOTE: Round your estimated standard error to 3 decimal places. Round your final answer to 4 decimal places)
Answer:
The lower interval limit for our 95% confidence interval is of 0.0412.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
We have taken a random sample of 100 observations and observed 10 instances of the characteristic in question.
This means that [tex]n = 100, \pi = \frac{10}{100} = 0.1[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1 - 1.96\sqrt{\frac{0.1*0.9}{100}} = 0.0412[/tex]
The lower interval limit for our 95% confidence interval is of 0.0412.

Find the standard deviation of the given data rounded to the nearest hundredth. 5.6, 5.2, 4.6, 4.9, 5.7, 6.4
Answer:
Standard deviation = 0.59
Step-by-step explanation:
Given data → 5.6, 5.2, 4.6, 4.9, 5.7, 6.4
Mean of the given data = [tex]\frac{5.6+5.2+4.6+4.9+5.7+6.4}{6}[/tex]
= 5.4
Data (x) (x - mean) (x - mean)²
5.6 5.6 - 5.4 = 0.2 (0.2)² = 0.04
5.2 5.2 - 5.4 = -0.2 (-0.2)² = 0.04
4.6 4.6 - 5.4 = -0.8 (-0.8)² = 0.64
4.9 4.9 - 5.4 = -0.5 (-0.5)² = 0.25
5.7 5.7 - 5.4 = -0.3 (-0.3)² = 0.09
6.4 6.4 - 5.4 = 1 (1)² = 1
N = 6 [tex]\sum (x-mean)^2[/tex] = 2.06
Since, Standard deviation = [tex]\sqrt{\frac{\sum (x-mean)^2}{N}}[/tex]
= [tex]\sqrt{\frac{2.06}{6} }[/tex]
= 0.5859

This is about the cone formula. If you don't know it, please don't answer. If you do, PLEASE ANSWER.
9514 1404 393
Answer:
(b) 10.5 in
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3πr²h . . . . . . for radius r and height h
Then the height is ...
h = 3V/(πr²)
Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...
h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in
The height of the cone is about 10.5 inches.

Enter your answer as me like this: 42
Answer:
[tex]Rate = 3[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Average rate of change over [tex]1 \le x \le 3[/tex]
This is calculated as:
[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]
[tex][a,b] = [1,3][/tex]
[tex][f(a),f(b)] = [-2.4][/tex]
So, we have:
[tex]Rate = \frac{4 - (-2)}{3 - 1}[/tex]
[tex]Rate = \frac{6}{2}[/tex]
[tex]Rate = 3[/tex]

. A nationwide survey of college seniors by the University of Michigan revealed that almost 70% disapprove of daily pot smoking, according to a report in Parade. Suppose 12 seniors are selected at random and asked their opinion. Our goal is to investigate the number of pot smokers. (a) Verify that this is an example of a binomial experiment. (b) What is the probability that exactly one of the 12 seniors disapproves daily pot smoking
Answer:
a) Trials are independent, and there is a fixed number of trials, which means that the binomial probability distribution can be used.
b) 0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
a)
For each senior, there are only two possible outcomes. Either they disapprove daily pot smoking, or they do not. The seniors are selected at random, which means that the probability of one disapproving daily pot smoking is independent of other seniors, that is, the trials are independent. There is also a fixed number of trials.
b)
70% disapprove of daily pot smoking, according to a report in Parade, which means that [tex]p = 0.7[/tex]
12 seniors means that [tex]n = 12[/tex]
The probability is P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{12,1}.(0.7)^{1}.(0.3)^{11} = 0.000015[/tex]
0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
Seventy homes that were for sale in Tampa, Florida in Spring of 2019 were randomly selected. A regression model to predict house price was run based on first floor square footage and the indicator variable for Beach (1 if the house was within 1 mile of the beach, 0 if not). There was also an interaction term for firstfloorsquarefootage*Beach.
Term Estimate Std. Error
Intercept -93.4 214.5
Beach 782.5 31.45
firstfloorsquarefootage 0.412 0.120
firstfloorsquarefootage*Beach 0.004 0.012
How would you interpret the slope coefficient for firstfloorsquarefootage*Beach?
A. Homes near the Beach are less expensive than elsewhere for a given size.
B. The slope of the relationship between firstfloorsquarefootage and price is lesssteep for homes near the beach than elsewhere in Tampa
C. Homes near the Beach are more expensive than elsewhere for a given size.
D. The slope of the relationship between firstfloorsquarefootage and price is moresteep for homes near the beach than elsewhere in Tampa
Answer:
D.The slope of the relationship between first floor square footage and price is more steep for homes near the beach than elsewhere in Tampa
Step-by-step explanation:
We can see from the output that was run in this regression that this variable has a positive coefficient. So the result is going to be interpreted to show an increase. Therefore d is the answer as it shows that these homes which are closer to the beach are steeper compared to those that are in other areas of tampa. It's necessary to always look out for the signs of the coefficient when interpreting a regression result

What is an equation of the line that passes through the point (4,-1) and has a slope of -2?
Answer:
Option C, [tex]y = -2x + 7[/tex]
Step-by-step explanation:
1) Slope-intercept format is represented by the formula [tex]y = mx + b[/tex]. By looking at the options, we can see that all of them follow this format.
So, first, we can identify which equations have a slope of -2 to narrow down our options. In slope-intercept form, the coefficient of the x-term, or [tex]m[/tex], represents the slope. So, this narrows the answer down to options b and c because they are the only ones that have [tex]m[/tex] as -2.
2) Next, in order to find which equation is the right answer, we can substitute the x and y values of the given point (4, -1) into both equations, then simplify. Whichever equation results in a true statement must be the answer. Let's try option c first. Substitute 4 for x and -1 for y:
[tex]-1=4(-2)+7\\-1 = -8+7\\-1=-1[/tex]
-1 does equal -1, so this statement is true. Thus, option c must be the answer.
The equation of the straight line will be -
y = -2x + 7
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have an equation of the line that passes through the point (4,-1) and has a slope of -2.
Assume the equation of the line to be -
y = -2x + c
The line passes through the point (4,-1), so we can write -
-1 = -2 x 4 + c
-1 = -8 + c
c = -1 + 8
c = 7
Therefore, the equation of the straight line will be -
y = -2x + 7
