E2

A survey of prices for external disk drives found the accompanying data, where 1 TB = 1000 gigabytes. Some research on the prices discovered that the 190 GB hard drive was a special "hardened" drive designed to resist physical shocks. Because it is completely different from the other drives, it was removed from the data. The correlation is now 0.988 and other summary statistics are shown in the accompanying popup window. Complete parts a and b. Click the icon to view the original data. Click the icon to view the summary statistics for the data with the 190 GB hard drive removed. a) If a drive has a capacity of 4.00 TB (or 2 SD above the mean of 1.13 TB), how many standard deviations above or below the mean price of $125.67 do you expect the drive to cost? The expected cost is standard deviations the mean price. (Type an integer or decimal rounded to two decimal places as needed.)
