Ontario high school students must finish a minimum of six Ontario Academic Credits (OACs) to gain admission to a university in the province.Most students take more than six OACs because universities take the average of the best six in deciding which students to admit.Most programs at universities require high school students to select certain courses.For example, science programs require two of chemistry, biology, and physics.Students applying to engineering must finish at least two mathematics OACs as well as physics.In recent years, one business program began an examination of all aspects of its program, including the criteria used to admit students.Students are required to take English and calculus OACs, and the minimum high school average is about 85%.Oddly, even though students are required to complete English and calculus, the marks in these subjects are not included in the average unless they are in the top six courses in a student's transcript.To examine the impact of this policy on admissions decisions, the program director took a random sample of students who recently graduated with the BBA (Bachelor of Business Administration) degree.She recorded the university GPA (in the range 0 to 12), the high school average based on the best six courses, and the high school average using English and calculus and the next four best marks.These data are stored in the worksheet ssss.xls.(https://drive.google.com/file/d/1br_ivPMEMBPQ_YrZuYm30yskwbkoBoVS/view?usp=sharing)

a)Is there a relationship between university GPA and the high school average using the best six OACs?

b)Is there a relationship between GPA and the high school average using the best four OACs plus calculus and English?

c)How should the program director interpret the implications of this data for admission purposes?
