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.10.6, 9.8, 10.6, 10.4, 10.4, 10.5, 9.9, 9.8, 10.6, 10.30Click here to view page 1 of the table of critical values of the t-distribution.Click here to view page 2 of the table of critical values of the t-distribution.(a) Choose the correct H, and H, below.O A.
