Athletes are interested to know whether their Transition 1 time from swim to bike in a sprint triathlon is the same as in a super sprint triathlon. Consider the 2013 male triathletes who competed in both the Individual Sprint Triathlon (sprint) and in the Team Relay Triathlon (super sprint) as a sample of all male triathletes. Details of their race times can be found in the Excel sheet “2013 Men Sprint & Super Sprint”. (Hint: The athlete’s individual performance in a Team Relay is their Super Sprint data.) a) Consider the differences for Transition 1 times between a sprint triathlon and a super sprint triathlon. (Hint: The sample data are matched pairs. Explain why.) Find the sample mean and sample standard deviation for the differences.   b) Is there enough evidence at the 10% significance level to conclude that the average Transition 1 time is different in a sprint than in a super sprint? (Hint: Use the results of a) and apply the t-test for difference of population means.) Provide a possible explanation for the difference you did or did not observe.   c) Estimate, with 90% confidence, the population mean difference in Transition 1 times between a sprint and super sprint. Interpret the result. (Hint: Use the results of a) to construct a confidence interval estimate using the t-distribution.)
