Do wet suits allow a swimmer to swim faster? Researchers measured the speed (in meters per second) of swimmers both with and without a wetsuit. The results of the study are shown in the table. Conduct the appropriate test to determine whether the data suggest that wet suits allow a swimmer to swim faster. Be sure to check all model requirements. Use an a = 0.05 level of significance. If you reject the null hypothesis, estimate the average difference in speed of the swimmer with the wet suit with 95% confidence.
