In a statistics course, a linear regression equation was computed to predict the final-test score from the score on the first quiz. The resulting equation was: ˆy = 25 + 0.84x with a correlation of 0.73 where y is the final test score and x is the score on the first quiz. (a) If Carla scored 82 points on her first quiz, what is the predicted value of her score on the final test? (b) The linear regression line predicted...

Data are collected for the scores y of n = 10 randomly selected students from a statistics class and the number of hours x they slept the night before the attempt. Summary statistics are x = 4.2, sx = 1.874, and se = 6.305; the least squares line is  = 5.044x + 56.11. Construct a 95% prediction interval for the mean attempt score of a particular student that got x = 5 hours of sleep the night before the attempt (use...

A chemistry class had two tests. On the first test the mean score was 70 with a standard deviation of 10. On the second test the mean score was 60 with a standard deviation of 15. The correlation coefficient between the scores of the two tests was r = 0.6. We run a regression analysis with the first test score as the independent variable and the second test score as the dependent variable. We use the result to estimate the...
