In а study оf оnline vs. in-persоn stаtistics courses, а researcher wishes to test the claim that the average student grade in online stats courses is higher than than average student grade in in-person stats courses. To test this claim 60 online student's grades are randomly selected, with an average of 86.8 and a standard deviation of 5.25. In addition, 70 in-person student's grades are randomly selected, with an average of 85.0 and a standard deviation of 6.37. Based on this data, and using an alpha=0.05, answer the following questions.The left critical value = [left] (round to 2 decimals - if there is no left value, enter "na")The right critical value = [right] (round to 2 decimals - if there is no right value, enter "na")The test statistic = [ts] (round to 2 decimals)The result of the hypothesis test is [result] (enter "reject H0" or "fail to reject H0")Is the claim supported? [support] (enter "yes" or "no")
