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 0.10 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. 9.8, 9.7, 9.6, 10.1, 10.1, 10.5, 9.8, 9.6, 10.1, 9.6 Click here to view rage 1 of the table of critical values of the t-distribution.
