Manufacturer of a CNC machine claims that the average warm-up time for their machine is 10 minutes. We would like to test this claim at a 0.01 significance level and therefore run 10 trials that result in the following warm-up durations (in minutes). Warm-up durations are assumed to follow a Normal distribution. 10.2, 9.6, 9 6, 10.3 , 10.2, 10 2, 96, 9 8, 10 1, 10.1 0 Click here to view page 1 of the table of critical values of the t-distribution.
