In the Boston Marathon, there has been a wheelchair division since 1977. A researcher would like to know who is typically faster, the men's marathon winner on foot or the women's wheelchair marathon winner. Because the conditions differ from year to year, and speeds have improved over the years, it seems best to treat these as paired measurements. The summary statistics for the pairwise differences in finishing time (in minutes) are as shown. Complete parts a and b. Mean= -8.768 Summary of wheelchrF-runM n=43 EZZE The confidence interval is minutes. (Round to two decimal places as needed.) SD=32.989 a) Assuming that these times are representative of such races and the differences appeared acceptable for inference, construct and interpret a 95% confidence interval for the mean difference in finishing times.
