Hi

I need help with the following questions. It is chapter 4 section 4.5 of the book: Essentials of Business Analytics+ LMS Integrated for CengageNOW 1-Semester Printed Access Card(First Edition) Camm, Cochran, Fry, Ohlmann, Anderson, Sweeny, and Williams Cengage Learning 2015 iSB-10: 1-305-61560-3 ISBN: 978-1-305-61560-1

Problem 4-9

Dixie Showtime Movie Theaters, Inc., owns and operates a chain of cinemas in several markets in the southern U.S. The owners would like to estimate weekly gross revenue as a function of advertising expenditures. 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
Jackson	75.8	4	1.5
Birmingham	127.8	4.3	4
Little Rock	137.8	3.5	4.3
Biloxi	101.4	3.6	2.3
New Orleans	237.8	5	8.4
Baton Rouge	219.6	6.9	5.8

(a)	Use the data to develop an estimated regression with the amount of television advertising as the independent variable.
Letxrepresent the amount of television advertising.
If required, round your answers to four 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.
Letx1represent the amount of television advertising.
Letx2represent the amount of newspaper advertising.
If required, round your answers to four decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300)
=+x1+x2
Is the overall regression statistically significant at the 0.05 level of significance? If so, then test whether each of the regression parameters0,1, and2is 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.
