Marathon start-up years 2010 When we considered theBoston Marathon in Exercise 37, we were unable tocheck the Nearly Normal Condition. Here’s a histogramof the differences:Those three large differences are the first three years ofwheelchair competition: 1977, 1978, and 1979. Often thestart-up years of new events are different; later on, moreathletes train and compete. If we omit those three years,the summary statistics change as follows:Summary of wheelchrF - runMN = 31Mean = -12.794SD = 18.64a) Comment on the assumptions and conditions.b) Assuming that these times are representativeof such races, construct and interpret a 95%confidence interval for the mean difference infinishing time.c) Would a hypothesis test at a = 0.05 reject the nullhypothesis of no difference? What conclusion wouldyou draw?

Coffee and blood pressure. A scientist suspects that coffee increases blood pressure. So, he measures the systolic blood pressure of six random patients and then measures it again 30 minutes after they drink a single cup of caffeinated coffee. The results are tabulated below. Test the claim that coffee causes an increase in blood pressure. Before Coffee 123 114 100 120 112 115 After Coffee 123 119 102 121 112 118 (a) Why are these paired data? O This table does not have paired data; there is no clear relationship between the data in each column. O Each column contains data from the same patient. O Most of the 'After Coffee' values are smaller than the corresponding 'Before Coffee' values. O The after and before rows are the same size. (b) Write the hypotheses in symbols. Note that this problem uses Haiffabefore-after instead of Pdiff-after-before so be careful. O H;: Pdiffabefore-after = 0 H3: Pdiff-before-after 0 O Ho: Hdiffabefore-after H3: Pdiffabefore-after = 0 = 0 OH,:…
