 Disk drives have been getting larger. Their capacity is now often

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 study of external disk drives finds the data available below. The least squares line was found to be Price = 16.17 + 61.033 Capacity with s. = 45.80 and SE (b1 ) = 12.3410. Complete parts a through c below. Click the icon to view the external disk drive data. a) Find the predicted Price of a 2 TB hard drive. The predicted Price of a 2 TB hard drive is $ (Round to the nearest cent as needed.) X External disk drive data b) Find the 95% confidence interval for the mean Price of all 2 TB disk drives. Capacity (TB) Price ($) (Round to two decimal places as needed. Do not include the $ symbol in your answer.) 0.15 34.00 0.25 37.95 c) Find the 95% prediction interval for the Price of a 2 TB hard drive. 0.32 50.50 85.00 N 105.00 (Round to two decimal places as needed. Do not include the $ symbol in your answer.) 3 130.00 A 325.00 Mean 1.53 109.64 SD 1.51 101.47 Print Done
