Question

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. For the remaining 7 drives, the correlation is now 0.927 and other summary statistics are:
a) If a drive has a capacity of 3.046 TB (or 1 SD above the mean of 1.531 TB), how many standard deviations above or below the mean price of $110.70 do you expect the drive to cost?
b) What price does that correspond to?
