There аre nо mоre questiоns on the exаm. When you аre ready to submit the exam, you may go ahead and do so using the submit button for the exam on Brightspace. There will be no answers entered in any of the fields for the questions. You will basically submit an empty online exam. But your answers to the questions are on your scratch paper, along with your work. Once you submit your exam on Brightspace, you will have 10 minutes to submit all pages of your exam to Dean Patrick Knisley. You should turn on your cell phone that you were asked to bring, take pictures, and email him all pages. His email is patrick_knisley@fitnyc.edu. If it takes longer than 10 minutes from the time you submit the empty exam on Brightspace and when you send pictures of all exam pages to Dean Knisley, then the exam grade will be a zero.
Plаce yоur nаme оn аll pages. Number apprоpriately, and solve on your paper. You must show all work to receive credit. Answer according to methods presented in the class or textbook. Partial credit is possible. ----------------------------------------------------------------- We develop a regression model to predict sales for your business, using data from ad expenses and number of website visitors. Below, we observe partial results of running a multiple regression: Multiple R 0.96959148 R Square 0.94010764 Adjusted R Square 0.93012557 Standard Error 42935.3013 Observations 15 ANOVA df SS MS F Significance F Regression 2 3.47229E+11 1.74E+11 94.17971 4.61561E-08 Residual 12 22121281145 1.84E+09 Total 14 3.69351E+11 Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept -47659.3804 39288.98722 -1.21305 0.248451 -133262.7298 37943.969 Ad Expenses 8.65784561 0.86055659 10.06075 3.35E-07 6.782853871 10.5328373 Website 1.11501697 0.527431253 2.114052 0.056126 -0.034157011 2.26419095 a. (5 pts) State the multiple regression equation. b. (10 pts) The slope for website visits is 1.11. Provide the proper interpretation for this slope (m2{"version":"1.1","math":"m2"}). It begins as follows ... "For a fixed cost in ad expenses, average sales are ...." c. (10 pts) Test the significance of the overall multiple regression model at α=0.05{"version":"1.1","math":"α=0.05"}. by: (1) stating the null and alternative hypotheses, (2) drawing the diagram showing the F test statistic and F cutoff value, and (3) stating whether you accept or reject the null. d. (10 pts) If the results from c. above deem it appropriate, determine which of the variables (ad expenses, website visits, or both) have a significant influence on sales. Draw the diagrams showing the specific t test statistics and t cutoff values. If the results do not deem it appropriate, say why it does not make sense to perform these tests.
