A biologist believes that the gestation period for a mouse is not 21 days, as reported. She decides to randomly select 35 mice and record their gestation times, in days. The results are given in the following table: 22 21 22 20 19 20 23 24 20 24 24 20 20 24 23 23 21 22 20 22 22 23 21 22 23 21 20 21 22 22 24 21 24 21 22 g. Is there evidence to suggest that the average gestation period for a mouse is different from 21 days? Use a=0.05. Be sure to complete all of the necessary steps of the hypothesis test. No need to show work for calculations.
