Test the slope of the regression line, y = -46.292 + 15.240 x of the following data. Use a = .10 and Se = 108.7. Advertising Sales 12.5 148 3.7 55 21.6 338 60.0 994 37.6 541 6.1 89 16.8 126 41.2 379 (Round the intermediate values to 3 decimal places. Round your answer to 2 decimal places.) Observed t = 0.1402 The decision is to reject the null hypothesisThe following data published by the U.S. Small Business Administration, Office of Advocacy, are pairs of the number of business bankruptcies (1000s) and the number of firm births (10,000s) for a six-year period. Solve for the standard error of the estimate (by using the predicted values of y and the residuals) and comment on it.
