5. Computer Power Supply Units (PSU) from two distinct businesses, U and V, are being tested by a benchmark company. To test for overvoltage protection, PSUs were put under 120% stress. The following information, which is shown in the following Table, shows the time to failure (in hours) for random samples chosen from the firms' daily output. Failure time (in hours) of PSU of U and V Company Company Failure time (in hours) U 0.54 1.80 4.52 2.05 1.03 1.18 0.80 1.33 1.29 1.11 3.34 1.54 0.08 4.12 0.60 0.72 0.92 1.05 1.66 3.03 1.81 2.17 0.63 0.56 5.03 0.09 0.18 0.34 1.51 1.45 V 1.52 0.19 1.55 0.02 0.07 3.65 0.40 0.24 1.66 1.45 1.60 1.80 4.69 0.08 7.89 1.58 0.64 0.03 0.23 0.72 a) What are the sample size of the company U & V individually? b) Compute the sample mean, variance, and standard deviation for the time to failure for company U. c) Compute the sample mean, variance, and standard deviation for the time to failure for company V. d) Compute the Coefficient of variation for the time to failure for company U. e) Compute the Coefficient of variation for the time to failure for company V. f ) Which measure one should consider to compare the performance/consistency of the product of the two company? And why? g) Which company's product is more consistent in its performance
