Question: In a study of alcoholics, a significant correlation has been found between blood alcohol concentration (BAC) and the score on a 50-item test of recent memory. The average BAC in the persons studied was .01% with s=.004, and the average number of items correctly answered on the recent memory test was 35, s=6. Assuming a correlation of -.83, find the regression equation and predict the score of a person with a BAC of .015%.
