In Applied Life Data Analysis (Wiley, 1982), Wayne Nelson presents the breakdown time of an insulating fluid between electrodes at 34kV. The times, in minutes, are as follows: 0.18, 0.78,0.97, 1.27,2.89, 3.06, 4.09, 4.61, 4.88, 6.42,7.47,8.06, 8.36, 12.80, 31.79, 32.62, 33.86, 36.80, and 72.73. Calculate the sample mean and sample deviation of the breakdown data. Round your answers to 2 decimal places. Mean= Standard Deviation- minutes minutes
