Professor Frankel is trying to determine if there is a difference in average grades for MTH107 students based on whether the take a face-to-face or an online class. She collects a sample from a few sections of MTH107 taught face-to-face and finds that the average grade of the 98 students is 75.2% with a sample standard deviation of 3.25%. In a sample of online sections of MTH 107 she finds that the average grade of 59 students is 73.5% with a sample standard deviation of 5.4%. Can she conclude that there is a difference in average grades between these types of courses? Use a 0.05 level of significance. Assume the population standard deviations are not equal. Round all numerical answers to 4 decimal places. The test statistic (t or z) Question Blank is = Question Blank . The p-value is = Question Blank . Therefore, we (reject or do not reject) Question Blank the null hypothesis that the averages are the same. We can conclude that there (is or is not) Question Blank evidence to support the conclusion that there is a difference in average grades between the two types of clas
