Question: Here are prices for the external disk drives we saw in Chapter 15, exercise 10: The least squares line is Price = 15.11 + 62.417

Here are prices for the external disk drives we saw in Chapter 15, exercise 10:

The least squares line is Price = 15.11 + 62.417 capacity.
The assumptions and conditions for regression are met.
SE (b1) = 11.33 and se = 42.04
a) Disk drives keep growing in capacity. Some teach experts now talk about Petabyte (PB = 1000 TB = 1,000,000 GB) drives. What does this model predict that a Petabyte-capacity drive will cost?
b) Is this prediction likely to be useful? Explain.

Capacity (in TB) Price(in) 0.15 0.25 0.32 1.0 2.0 3.0 4.0 1.53 35.00 39.95 9.95 75.00 110.00 140.00 325.00 7 1107 SD()- 1515 ) 102049
