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.

K Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB = 1000 gigabytes, or about a trillion bytes. A survey of prices for external disk drives found the data shown to the right. For this data, we want to predict Price from Capacity. Complete parts a through i below. Click the icon to view the disk drive data and summary statistics. Disk Drive Data and Summary Statistics Capacity (in TB) 0.5 1.0 2.0 3.0 4.0 6.0 8.0 12.0 32.0 x = 7.611 SD(x) = 9.85 r = 0.987 --- Print Price (in $) 58.79 75.79 114.00 105.95 146.45 425.49 594.00 1074.00 4464.49 y = 784.329 SD(y) = 1420.27 Done X A. It indicates the price for a hard drive with no capacity. It is meaningless and should not be interpreted. B. It indicates the additional capacity in TB for each additional dollar of price. It is meaningful in that it could be interpreted as the cost of the parts common to all drives.
