The study of external disk drives from Chapter 4, exercise 2 (with the outlier removed) find the following:

The least squares line was found to be: Price = 15.112 + 62.417 Capacity with se = 42.037 and SE(b1) = 11.328.
a) Find the predicted Price of a 2 TB hard drive.
b) Find a 95% confidence interval for the mean Price of 2 TB disk drives.
c) Find the 95% prediction interval for the Price of a 2 TB hard drive.

Capacity (TB) 0.15 0.25 0.32 Price (S) 35 39.95 49.95 75 110 140 325 110.7 102.05 Mean SD 1.53 1.51
