A study reported in "Inside Higher Education News" (May, 2006) found that financial incentives can improve low-income college students' grades and retention. As part of their "Opening Doors" program, a Louisiana community college offered to pay students $1,000 per semester on condition that they maintain at least half-time enrollment and at least a 2.0 GPA.

b) The Mean GPA of Opening Doors students was 2.3 as compared to the mean GPA of 2.1 for traditional students. Identify the target parameter for this comparison.
