A casino is interested in the relationship between the amount of alcohol people buy and the amount of money they spend at the slot machines. They have sampled 10 people and measured the amount of alcohol they drank and how much they spend that day. Based on the regression line, they would like to predict how much money people will spend based on the amount that they drink. The data are below. Alcohol by the Ounce Ounces purchased Dollars spent on slots .5 35 1 64 2 100 1 73 2.5 110 3 150 1.5 130 5 300 3 130 2.5 105 If the regression line is: y = 50.87x + 7.78, How much money do we predict that a person who drinks 2.57 ounces of alcohol spends? Round to 2 decimal places. Do not put a dollar sign in your answer.
