Data for a sample of eight markets for a recent week follow.     Market Weekly Gross Revenue ($100s) Television Advertising ($100s) Newspaper Advertising ($100s)   Mobile 102.5 5.1 1.6     Shreveport 52.7 3.2 3.0     Jackson 75.8 4.0 1.5     Birmingham 127.8 4.3 4.0     Little Rock 137.8 3.5 4.3     Biloxi 101.4 3.6 2.3     New Orleans 237.8 5.0 8.4     Baton Rouge 219.6 6.9 5.8       (a) Use the data to develop an estimated regression equation with the amount of television advertising as the independent variable.   Let x represent the amount of television advertising.   If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300)    =  +  x   Test for a significant relationship between television advertising and weekly gross revenue at the 0.05 level of significance. What is the interpretation of this relationship?   The input in the box below will not be graded, but may be reviewed and considered by your instructor.           (b) How much of the variation in the sample values of weekly gross revenue does the model in part (a) explain?   If required, round your answer to two decimal places.    %     (c) Use the data to develop an estimated regression equation with both television advertising and newspaper advertising as the independent variables.   Let x1 represent the amount of television advertising.   Let x2 represent the amount of newspaper advertising.   If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300)    =  +  x1 +  x2       Test whether each of the regression parameters β0, β1, and β2 is equal to zero at a 0.05 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable?   The input in the box below will not be graded, but may be reviewed and considered by your instructor.           (d) How much of the variation in the sample values of weekly gross revenue does the model in part (c) explain?   If required, round your answer to two decimal places.    %
