STATISTICS Stock market analysts are continually looking for reliable predictors of stock prices.  Consider the problem of modeling the price per share of electric utility stocks (Y-dependent variable).  Two variables thought to influence such stock prices are the return on average equity (X1) and annual dividends (X2).  Using the stock prices, return on average equity and dividend rates on a randomly selected day for 16 utility stocks resulted in the regression output below.   Make a prediction of a utilities stock price if the average return on equity is [RAE] and the dividend rate is [DY] (answer to two decimals i.e. XX.xx)

Consider the figure below that denotes ASes and their relationships.   Note:  C1, C2, C3 are customers of ISP-X. ISP-P is a provider of ISP-X.       ISP-X has the incentive to advertise routes for C3 to Y.
