A computer repair firm believes that its average repair time isless than two weeks. Using the accompanying data that gives thecomputer repair times in days, determine if the company cancontinue to support this claim. Use a level of significance of0.05.
Is there sufficient evidence at the 0.05 level of significancethat the average repair time is less than two weeks?
Determine the null hypothesis, H0, and the alternativehypothesis, H1.
Compute the test statistic.
(Round to two decimal places as needed.
Find the p-value for the test.
State the conclusion.
The p-value is less than or greater than the chosen value ofα, so do not reject or reject the null hypothesis. There issufficient or insufficient evidence to conclude that the populationmean is less than two weeks
