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.
