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.
