A media company is in the process of deciding whether to purchase a maintenance contract for a new piece of camera equipment or pay for the maintenance themselves. Managers feel that costrequired to maintain the equipment should be related to the amount of time it is used, and they collected the following data on hours used (per week) and yearly maintenance costs (in dollars).Hours Used per Week9 =12101927311723314037Maintenance Cost per Year1750225029503650475030003200385051004050(a) Develop the estimated regression equation that could be used to predict the yearly maintenance costs (in dollars) given the weekly usage (in hours). (Round your numerical values to twodecimal places.)

When the two variables are said to be associated with each other, one variable is used to find the…
