In 10000 meter race, runners complete over 25 laps or a 400 meter track. It is the longest track running event held. The men's 10000 meter began at the 1912 Olympics. It was 1988 (over seventy years later) before the women's 10000 meter was added to Olympic competition. The official world records in the 10,000 meters are held by Kenenisa Bekele with 26:17.53 minutes for men and Almaz Ayana from Ethiopia with 29:17.45 minutes for women. In this project, we are going to take a look at the 2016 Rio Olympics men and women 10000 meter competition. All the times for the participant's times are given to you in minutes. You should leave the times in minutes and round to the nearest thousandth when needed. Assume the populations are normally distributed. 1. Use the samples to find the mean completion time of the for the a. male runners. b. female runners. 2. Use the samples to find the sample standard deviation of the completion times for the a. male runners. b. female runners.

Big Bear lake has 22 miles of shoreline and is an ideal place for paddle boarders. A researcher wants to know if the time it takes to paddle board across Big Bear Lake decrease when the paddle boarder listens to music? Nine paddle boarders were timed as they paddle boarded across Big Bear Lake while listening to music and again while not listening to music. The resulting times, in minutes, are shown in the table below. Paddle Boarding Time to Cross Big Bear Lake Listened to Music No Music 44 38 49 50 40 45 45 41 54 47 44 52 50 42 53 44 47 59 Assume a Normal distribution. What can be concluded at the the a = 0.10 level of significance? For this study, we should use t-test for the difference between two dependent population means a. The null and altenative hypotheses would be: Ho: pd H: pd μα b. The test statistic t v= -3.600 (please round your answer to 3 decimal places.) %3D c. The p-value = 0.0035 (Please round your answer to 4 decimal places.) d. The p-value is sva e. Based on this,…
