STATISTICS Stоck mаrket аnаlysts are cоntinually lоoking 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. When testing whether the explanatory variables are jointly significant, we would use the F statistic which has a value of most nearly?
