The expense ratio of a mutual fund measures the percentage of the fund's assets used to pay for annual administrative overhead. Funds with higher ratios spend more of the fund's return to operate the fund. A random selection of 16 stock mutual funds last year revealed the following data:

-Construct a scatter plot of the data. Clearly label each axis.

-Take the scatter plot created earlier and draw the least squares line on it.

-Find the equation for the least squares line of best fit.

-State the values of the regression coefficients (intercept and slope) and interpret what they mean. Does expense hurt or help the fund's return?

-Based on your regression analysis of the data, when is the average total return for a mutual fund with an expense ratio of 0.75%?
