Q2BHi wonderful Bartleby team, I need help with this two final parts of the exercise of completing the sentence and the last part of it as well (both marked in red)Sentense says:( Yes, No )because the confidence interval contains(Only positives / Only Negatives / Zero ) A study was conducted on the body temperatures of men and women. The table below displays the results. The two samples are independent simple random samples from normally distributed populations, and the population standard deviations are equal.| | Men (μ₁) | Women (μ₂) ||--------|-----------|------------|| n | 11 | 59 || x̄ | 97.68°F | 97.35°F || s | 0.97°F | 0.71°F |### Task a: Hypothesis TestingUse a 0.01 significance level to test the claim that men have a higher mean body temperature than women.**Null and Alternative Hypotheses:**- A: \( H_0: \mu_1 \geq \mu_2 \), \( H_1: \mu_1 < \mu_2 \)- B: \( H_0: \mu_1 \neq \mu_2 \), \( H_1: \mu_1 < \mu_2 \)- C: \( H_0: \mu_1 = \mu_2 \), \( H_1: \mu_1 \neq \mu_2 \)- D: \( H_0: \mu_1 = \mu_2 \), \( H_1: \mu_1 > \mu_2 \)**Chosen Hypotheses:**- D: \( H_0: \mu_1 = \mu_2 \), \( H_1: \mu_1 > \mu_2 \)**Test Statistic:**- \( t \) = 1.33 (rounded to two decimal places)**P-value:**- 0.094 (rounded to three decimal places)**Conclusion:**- Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women.### Task b: Confidence IntervalConstruct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women.- \( < \mu_1 - \mu_2 < \) (round to three decimal places)**Does the confidence interval support the conclusion from the hypothesis test?**- Choose the correct option: [Drop-down box](Note: The exact values for the confidence interval and the final decision on

A students wants to estimate the proportion of professors who drive pickup trucks. She surveys 250 professors from across the country and uses the results to construct a 90% confidence interval estimate of p, the proportion of all professors who drive pickup trucks. If she were to do this with a total of 86 different sample of 250 professors, yielding 86 different 90% confidence interval estimates of p, approximately how many intervals would contain the true value of p? Number of intervals = nothing (enter a whole number)

Congratulations, you just made a confidence interval! But wait, how did we decide on the width of the interval? The middle of the interval is the sample mean. We start there, and then the "wiggle room" we give on either side of that center is called the margin of error (MOE). There's a formula for margin of error: 0 MOE = 2* √T This formula consists of three values: o is the standard deviation, n is the sample size, and z is a multiplier that we choose based on the confidence level we need. Confidence levels are expressed as percentages, the most common are 90%, 95%, and 99%: * Confidence Z Level value 90% 1.645 95% 1.96 99% 2.576 Let's practice computing a margin of error. For our earlier example about houses, suppose the standard deviation was 14 years, and the sample size was 30. Use a confidence level of 95% and determine the margin of error: σ Remember, we'll use the formula MOE = 2* . First fill in the numbers for each part of the formula: √n = σ= n = Now put it all together,…
A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie Among the 500 respondents, 13% chose chocolate pie, and the margin of error was given as +4 percentage points. What values do p, q, n, E, and p represent? If the confidence level is 95%, what is the value of a? The value of p is The value of q is The value of n is The value of E is The value of p is If the confidence level is 95%, what is the value of a? (Type an integer or a decimal. Do not round.)
