Suppose a regional computer center wants to evaluate the performance of its memory system. one measure of performance is the average time between failures of its disk drive. to estimate the value, the center recorded the time between failures for a random sample of 45 drive failures. the sample mean has been computed to be 1,762 hours and the sample standard deviation is 215. estimate the true mean time between failures with a 90% confidence interval? interpret the confidence interval.
