MATH 533 Course Project Part C Regression Model Keller 2023. The correlation coefficient between sales and calls is calculated as 0.871. This positive correlation coefficient tells us that as the number of calls increase so does the number of sales. Correlation: Sales, Calls (Appendix III) Minitab Result Pearson correlation of Sales and Calls = 0.871 P-Value = 0.000 4. Minitab Result: (See above Fitted Line Plot for below result) S = 2.05708 R-Sq = 75.9% R-Sq(adj) = 75.7% The coefficien...

MATH 533 Course Project Part C Regression Model Keller 2023. The regression analysis is telling us that for each additional call sales will go up by 0.202. Minitab Result Regression Analysis: SALES versus CALLS (Appendix II) The regression equation is SALES = 9.64 + 0.202 CALLS Math 3 3. The correlation coefficient between sales and calls is calculated as 0.871. This positive correlation coefficient tells us that as the number of calls increase so does the number of sales.

MATH 533 Course Project Part B, Hypothesis Testing. Hypotheses testing involves the testing of the null hypothesis and the alternative hypothesis. When testing the hypothesis either the null hypothesis or the alternative hypotheses is rejected. The value to a company knowing to accept or reject a hypothesis will aid in the decision making process. Information derived from hypothesis testing can aid in more timely decision. Requirement A: The average (mean) sales per week exceeds 41.5 per sa...

MATH 533 Week 7 Course Project Part C Regression and Correlation Analysis SALESCALL Project. Regression Analysis: Sales versus Calls The regression equation is Sales = 9.638 + 0.2018 Calls Ans. 3 Math 3 The correlation coefficient between sales and calls is calculated as 0 .871. This is positive correlation coefficient; it means there is positive relationship between sales and calls. If the number of calls are increased then sales will also be increased and vice versa. The calculated cor...

MATH 533 Week 7 Course Project Part C Regression and Correlation Analysis. It is evident with the help of scatter graph trend line that there is positive relationship between Sales and calls. If number of calls increases the sales also increase and vice versa. Ans. 2 With help of Minitab, the regression equation is mentioned below as: Minitab Result Regression Analysis: Sales versus Calls The regression equation is Sales = 9.638 + 0.2018 Calls Ans. 3 Math 3 The correlation coefficient ...
