A computer manufacturer estimates that its line of minicomputers has, on average,8.5days of downtime per year. To test this claim, an analyst contacts seven companies that own one of these computers and is allowed to access company computer records. It is determined that, for the sample, the average number of downtime days is5.7, with a sample standard deviation of1.3days. Assuming that number of downtime days is normally distributed, test to determine whether these minicomputers actually average8.5days of downtime in the entire population. Let= .01.
