The following data values are from a random sample of 40 college students; the data show the students€™ gender, American College Test (ACT) composite scores, and grade point averages (GPAs) after their first term in college.

a. Construct a scatter diagram of the data with ACT scores on the horizontal axis and GPA on the vertical axis, being sure to identify the male and female students.
b. Do the patterns for males and females appear to be the same, or are they different? Identify specific similarities and differences.
c. Assume that a student had an ACT score of 25. What would you predict that student€™s GPA to be at the end of the first term in college?
d. Does there appear to be any relationship between ACT scores and the first-term GPA?
