Why do some students do well in university while others struggle? To help answer this question, a random sample of first-year students at four universities was selected. Those who had a grade point average of more than 3.0 (group 1) and those who had a grade point average of less than 2.0 (group 2) were surveyed. For each student, researchers recorded the results of tests (scored 0 to 10) that measure the following. Interpersonal skills (strong social skills, ability to interact effectively)

Stress management (being able to work well under pressure or resist and delay an impulse) Do these data provide sufficient evidence to infer that students whose GPA is more than 3.0 score higher in interpersonal skills and stress management than students whose GPA is less than 2.0?
