Question

The owner of Showtime Movie Theaters, Inc., would like to predict weekly gross revenue as a function of advertising expenditures. Historical data for a sample of eight weeks follow.

Weekly Gross Revenue ($1000s)	Televison Advertising ($1000s)	Newspaper Advertising ($1000s)
97	6	1.5
90	2	2
95	5	1.5
93	3.5	2.5
95	3	4.3
95	3.5	3.3
95	3.5	4.2
95	4	2.5

a. Use alpha= 0.01 to test the hypotheses

Ho : Beta Sub1= Beta Sub2 =0

Ha : Beta Sub1 and/or Beta Sub2 is not equal to zero

for the model y=Beta Sub 0+ Beta Sub1 Xsub1+Beta Sub2 Xsub2+E , where

X1= television advertising ($1000s)

X2+ newspaper advertising ($1000s)

Compute the F test statistic (to 2 decimals). Use F table.

What is the p-value?

- Select your answer -less than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 2

What is your conclusion?

- Select your answer -The overall model is not significantThe overall model is significantItem 3

b. Use alpha =0.05 to test the significance of Beta1 . Compute the t test statistic (to 2 decimals). Use t table.

What is the p-value?

- Select your answer -less than .01between .01 and .02between .02 and .05between .05 and .10between .10 and .20between .20 and .40greater than .40Item 5

What is your conclusion?

- Select your answer -No significant relationship between television advertising and revenueSignificant relationship between television advertising and revenueItem 6

Should X1 be dropped from the model?

- Select your answer -No, x1 should not be dropped from the modelYes, x1 should be dropped from the modelItem 7

c. Use alpha=0.05 to test the significance of beta sub2 . Compute the t test statistic (to 2 decimals). Use t table.

What is the p-value?

- Select your answer -less than .01between .01 and .02between .02 and .05between .05 and .10between .10 and .20between .20 and .40greater than .40Item 9

What is your conclusion?

- Select your answer -No significant relationship between newspaper advertising and revenueSignificant relationship between newspaper advertising and revenueItem 10

Should X2 be dropped from the model?

- Select your answer -No, x2 should not be dropped from the modelYes, x2 should be dropped from the modelI

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
