This page You may use any technology oddressed in an experiment at Ohio State University Sixteen students volunteered to take part in How much does drinking beer increase the alcohol content of your blood This question was an experiment Before the experiment each of the students blew into a Breathalyzer to show that their blood alcohol content BAC was at the zero mark The student volunteers then drank a varying number between 1 and 9 of 12 ounce beers How much each student drank was assigned by drawing tickets from a bowl About 30 minutes later an officer from the OSU Police Department measured their BAC using the Breathalyzer machine Here are the data Student Beers BAC Student Beers BAC r 1 5 0 10 9 3 0 02 Explain briefly 2 2 0 03 10 5 0 05 3 9 0 19 11 4 0 07 4 8 0 12 12 6 0 10 5 Slope 3 0 04 13 5 0 085 6 7 0 095 14 7 0 09 7 3 0 07 15 1 0 01 8 a Suppose you want to estimate how a person s BAC is affected by the number of beers he or she drinks Make a scatterplot don t need to attach of BAC versus beers using the data in the table above Which variable did you choose to be the y variable and which did you choose to be the x variable Explain Explanatory or x variable Response or y variable Explanation b Find the correlation between BAC and beers Is the correlation an appropriate measure of the strength of the association between BAC and beers Is it appropriate c Find the least squares regression line for BAC on beers Interpret the slope and y intercept of the regression line LSRL 5 0 06 16 4 0 05
