A university wants to implement a support course model to help college algebra students do better in their classes. The university will try the model on a class of 35 students to determine how well it works. The average grade of the students with the support course is 71% with a standard deviation of 20%. The university compareş these students to the the other 180 college algebra students with no support course. The average grade of the college algebra students with no support course is 69% with a standard deviation of 18%. College algebra grades are normally distributed. At the 5% significance level determine if the average grade with support is greater than the courses that do not have a support course. Use the support course class as population 1. Give the hypotheses. Null: There is no difference in the average grade with those that have a support course and those that do not. Alternative: The average grade of students with a support class will be higher. Null: There is no difference in the average grade with those that have a support course and those that do not. Alternative: The average grade of students with a support class will be lower.
