A company which designs sports shoes has made an improvement to their popular running shoe. They hope that athletes wearing the new running shoe will be able to run faster over short distances. They will use a paired sample to determine whether the mean time to run 100 meters for sprinters wearing the new running shoe is less than the mean time to run the 100 meters for sprinters wearing the old running shoe. Determine the null and alternative hypotheses for the proposed hypothesis test. O A. Let u, denote the mean time to run 100 meters for sprinters wearing the new running shoe and let u, denote the mean time to run 100 meters for sprinters wearing the old running shoe. The null and alternative hypotheses are Ho: H1 H2 O B.

16% of all college students volunteer their time. Is the percentage of college students who are volunteers larger for students receiving financial aid? Of the 377 randomly selected students who receive financial aid, 72 of them volunteered their time. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v Select an answer (please enter a decimal) H: ? v Select an answer v (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly higher than 16% at a = 0.10, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is higher than…

Assume a significance level of a = 0.05 and use the given information to complete parts (a) and (b) below. Original claim: Less than 46% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.1652. a. State a conclusion about the null hypothesis. (Reject H, or fail to reject Ho.) Choose the correct answer below. O A. Fail to reject Ho because the P-value is less than or equal to a. O B. Reject Ho because the P-value is greater than a. O C. Fail to reject H, because the P-value is greater than a. O D. Reject H, because the P-value is less than or equal to a. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? O A. The percentage of adults that would erase all of their personal information online if they could is more than or equal to 46%. O B. There is sufficient evidence to support the claim that the percentage of adults that…
