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.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject. Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a=0.10. P=0.0411 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.01. OB. Fail to reject Ho because the P-value, 0.0411, is less than a =0.01. OC. Reject Ho because the P-value, 0.0411, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0411, is less than a = 0.01 (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0411, is greater than a = 0.05. OB. Fail to reject Ho because the P-value, 0.0411, is less than a = 0.05. OC.

Based on that information, determine the null and alternative hypotheses. Would this be a one-tailed hypothesis test or a two-tailed test?
A poll of 1081 Americans showed that 46.8% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.05 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
