Following are the elapsed times in seconds for a synthetic job were measured on two different computer services. Let X represent the time recorded in the first computer and Y represent the time recorded in the second computer. X: 100 110 113 90 85 111 123 80 90 92 125 133 120 120 98 134 185 Y: 120 120 98 134 95 70 100 130 121 140 140 100 111 123 100 a) At 1% significance level, test the hypothesis that the population mean of the elapsed time on the first computer is less than the elapsed time on the second computer. b) At 4% significance level, test the hypothesis that the population variance of the elapsed time on the first computer is at most 200 sec². Use Excel to calculate different statistical measures. Following are the elapsed times in seconds for a synthetic job were measured on two different computer services.
