Stats II Question ? [Prev. Q.] [Next Q.] [Prev. Chap.] [Next Chap.] [goto] *****


A law school finds the following relationship between LSAT scores and first-year scores.

average LSAT score = 650, SD = 80
average first-year score = 65, SD = 10, r = 0.60

The scatter diagram is football-shaped.

Consider the students who scored about 750 on the LSAT. The regression method shows that the average of their first year scores was over seventy points. The percentage of these students (i.e. those with LSAT 750) with first year scores between 70 and 80 is closest to:

  • 90%
  • 45%
  • 80%
  • 20%
  • 55%
    • *****
