Comparison of two web page designs. You want to compare the daily number of hits for two different webpage designs that advertise our indie rock band. You assign the next 30 days to either Design A or Design B, 15 days to each. a) Would you use a one-sided or two-sided significance test for this problem? Explain your choice. b) If you perform the significance test using alpha = 0.05, how large (positive or negative) must the t statistic be to reject the null hypothesis that the two designs result in the same average number of hits?
