The parameter to be tested in this scenario is the mean GPA of the university honors students. The university is interested in promoting graduates of its honors program by establishing that the mean GPA of these graduates exceeds 3.50. Therefore, the focus is on the honors program students, and specifically their mean GPA. Option A is incorrect because it refers to all university students, rather than just the honors program students. Option C is incorrect because it refers to the sample mean GPA, which is not the parameter being tested. Option D is incorrect because it refers to the proportion of honors students with a GPA exceeding 3.50, rather than the mean GPA of the honors students.
