10.23: How well does the # of beers a student drinks predict their blood alcohol content level (BAG)? 10 students volunteers at Ohio State University drank a randomly assigned number of 12-02 beers. 30 minutes later, a police officer measured their BAC. Here is the data: Student 1 2 3 4 5 6 7 8 9 10 Beers 5 2 9 8 3 7 3 5 3 5 BAC 0.10 0.03 0.19 0.12 0.04 0.095 0.07 0.06 0.02 0.05 a? = 5,37 = 0.0775, 5x = 2.3513y = 00509.5\" = 50,5yy = 0.023365\" = 0.96.5 = 0.02483 (3) Make a scatterplot of the data. (b) Find the equation of the least-squares regression line for predicting BAC (y) from number of beers (X) and add this to your line in part (a). (c) Find the coefficient of determination
