= Develop an estimated regression equation using annual income ($1000s) as the independent variable and annual credit card charges as the dependent variable. (Round your numerical values to the nearest integer.)

Compute R². (Round your answer to three decimal places.)

REALLY NEED HELP WRITING THE CASE REPORT PLEASE HERES INFORMATION

For the written report, you will need to answer the following three questions using the techniques you have learned in class (as those are the questions posted on WebAssign HW6-Q7 as well): Does a regression with annual income as the independent variable show an effect on credit card spending? Does a regression with household size as the independent variable show an effect on credit card spending? Does a regression containing both aforementioned independent variables show an effect on credit card spending? The written report will consist of two general sections. The first is a brief writeup addressing the issues at hand followed by a paragraph for each of the questions. In the paragraph be sure to summarize your results (especially in terms of business implications) and touch on the following: What is the question being answered? [E.g., we would like to study whether a familys annual income as the independent variable affects their credit card spending.] What statistical techniques were used to answer the question? What values (F-statistics, R2 , etc.) did you used to draw your conclusions? How could this impact the business? Which appendix has the information for this question?
