Suppose a researcher is testing the hypothesis Upper H 0: pequals0.4 versus Upper H 1: pless than0.4 and she finds the P-value to be 0.33. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. A. If the P-value for a particular test statistic is 0.33, she expects results no more extreme than the test statistic in about 33 of 100 samples if the null hypothesis is true. B. If the P-value for a particular test statistic is 0.33, she expects results no more extreme than the test statistic in exactly 33 of 100 samples if the null hypothesis is true. C. If the P-value for a particular test statistic is 0.33, she expects results at least as extreme as the test statistic in about 33 of 100 samples if the null hypothesis is true. D. If the P-value for a particular test statistic is 0.33, she expects results at least as extreme as the test statistic in exactly 33 of 100 samples if the null hypothesis is true. Choose the correct conclusion below. A. Since this event is unusual, she will reject the null hypothesis. B. Since this event is not unusual, she will reject the null hypothesis. C. Since this event is unusual, she will not reject the null hypothesis. D. Since this event is not unusual, she will not reject the null hypothesis.

A tire company guarantees that a particular brand of tire has a mean useful lifetime miles or more. A consumer testing agency sampled n = 10 tires on a test wheel that simulated conditions. The sample mean lifetimes (in thousands of miles) were as follows: 42 36 46 43 41 35 43 45 40 39 Construct a 98% CI for the mean lifetime of this particular brand of tire.

Fewer young people are driving. In 1983, 87 percent of 19 year-olds had a driver's license. Twenty-five years later that percentage had dropped to 75 percent (University of Michigan Transportation Research Institute website, April 7, 2012). Suppose these results are based on a random sample of 1200 nineteen year-olds in 1983 and again in 2008.a. At 95% confidence, what is the margin of error and the interval estimate of the number of nineteen year old drivers in 1983? Round your answers to three decimal places.Margin of error = (four decimal places)Interval estimate = tob. At 95% confidence, what tis the margin of error and the interval estimate of the number of nineteen year old drivers in 2008? Round your answers to four decimal places.Margin of error =Interval estimate = toc. Is the margin of error the same in parts (a) and (b)?- Select your answer -YesWhy, or why not?

A random sample of 24 items is drawn from a population whose standard deviation is unknown. The sample mean is x⎯⎯ = 880 and the sample standard deviation is s = 5. Use Appendix D to find the values of Student’s t. (a) Construct an interval estimate of μ with 99% confidence. (Round your answers to 3 decimal places.) The 99% confidence interval is from 877.371 to (b) Construct an interval estimate of μ with 99% confidence, assuming that s = 10. (Round your answers to 3 decimal places.) The 99% confidence interval is from 874.742 to (c) Construct an interval estimate of μ with 99% confidence, assuming that s = 20. (Round your answers to 3 decimal places.) The 99% confidence interval is from 869.484 to (d) Describe how the confidence interval changes as s increases.
