a. Develop the estimated regression equation that relates annual maintenance expense (in hundreds of dollars) to weekly usage hours (to 3 decimals).

Expense = ___ + ___ Weekly Usage

b. Test the significance of the relationship in part (a) at a .05 level of significance.

-Compute the value of the F test statistic (to 2 decimals).

-The p value is -less than .01 or between .01 and .025 or between .025 and .05 or between .05 and .10 or greater than .10?
