Chemistry class had two exams. on the first exam the mean score was 70 with a standard deviation of 10. on the second exam the mean score was 60 with a standard deviation of 15. the correlation coefficient between the scores of the two exams was r = 0.6. we run a regression analysis with the first exam score as the independent variable and the second exam score as the dependent variable. we use the result to estimate the score on the second exam for each student based on their score on the first exam. for at least 75% of the students in the class, the regression estimated score for the second exam will be correct to within how many points?
