A law school finds the following relationship between LSAT scores and first-year GPAS: average LSAT score 165, SD 10 average first-year GPA≈ 65, SD≈ 5, r≈ 0.6 The scatter diagram is football-shaped. One of these students is chosen at random, and you are asked to estimate her first-year GPA, without being told her LSAT score. a. What would you estimate for her first-year GPA? Answer: b. What r.m.s. error would you expect for this estimate? i. 5 ii. 10 iii. √1-0.6² × 5 iv.√1-0.6² × 10 Choose one: Oi ii Oiii Oiv. Later you find that the student's LSAT score is 175. a. Now what would you estimate for her first-year GPA? Answer: b. What r.m.s. error would you expect for this estimate? i.5 ii. 10 iii. √1-0.6² × 5 iv.√1-0.6² × 10 Choose one: i O iii Oiv.
