An interesting research question is an effect, if any, that different types of teaching formats have on the grade outcomes of students. To investigate this issue one sample of students' grades was taken from a hybrid class and another sample taken from a standard lecture format class. Both classes were for the same subject. The mean course grade in percent for the 38 hybrid students is 83.87 with a standard deviation of 9.03. The mean grades of the 25 students form the standard lecture class was 70.18 percent with a standard deviation of 9.76. What is the Test Statistics to test the null hypothesis Ho : P1 " P2 against the alternative hypothesis Ha: 1 * p2?
