An agency collects data on various aspects of housing costs. Here's a scatterplot of the
Housing Cost Index (HCI) versus the Median Family Income (MFI). The correlation is r=0.69.
The mean HCI is 328.9, with a standard deviatioi of 111.06. The mean MFI is $46234, with a
standard deviation of $7042.75. Complete parts a through f.

b) What is the equation that predicts housing cost index from Median Family Income?
HCI =+(MFI
(Round the final answer to four decimal places as needed. Round all intermediate values to four decimal places as needed.)
c) For a particular area with MEL = $44,993, what would be the predicted HCI?
