For the hard drive data in Exercise 2, some research on the prices discovered that the 200 GB hard drive was a special

“hardened” drive designed to resist physical shocks and work under water. Because it is completely different from the other drives, it was removed from the data. The correlation is now 0.994 and other summary statistics are:

a) If a drive has a capacity of 2.55669 TB (or 1 SD above the mean of 1.100 TB), how many standard deviations above or below the mean price of $133.98 do you expect the drive to cost?

b) What price does that correspond to?
