Transcribed Image Text: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 0.05 significance level and therefore run 10 trials that result in the folowing warnm-up durations (in minutes). Warm-up durations are assumed to follow a Normal distribution.
