A survey of prices for external disk drives found the accompanying data, where 1 TBequals 1000 gigabytes. Some research on the prices discovered that the 210 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 0.995 and other summary statistics are shown in the accompanying popup window. Complete parts a and b.
