Question
To predict blood alcohol content of a student who drank 5 beers will be about?
How well does the number of beers a student drinks predict his or her blood alcohol content? Sixteen student volunteers at Ohio State University drank a randomly assigned number of cans of beer. Thirty minutes later, a police officer measured their blood alcohol content. A scatterplot of the data appears below. Based on this data the least-squares regression line for predicting blood alcohol content from the number of beers is â = 0.013 +0.018. A plausible value of the correlation between number of beers and blood alcohol content, based on the scatterplot, is Blood alcohol content 0.25 0.20- 0.15- 0.10- 0.05- 0.0- 0 1 2 3 4 5 67 8 9 10 Number of beers
