MATH 534 APPLIED MANAGERIAL STATISTICS Week 7 Course Project Part C Regression and Correlation Analysis. 1. Generate a scatterplot for the specified dependent variable (Y) and the X1 independent variable, including the graph of the "best fit" line. Interpret. Fitted Plot Line 0 10 20 30 40 50 60 According to the Graph the linear relationship there is a positive relationship between Sales and calls. If number of calls increases the sales also increase and the same if sales increases the calls increases. COURSE PROJECT: PART C 3 2. Determine the equation of the "best fit" line, which describes the relationship between the dependent variable and the selected independent variable. y = 0.0707x + 31.2 3. Determine the coefficient of correlation. Interpret. The correlation coefficient between sales and calls is calculated as 0.. This is a moderate positive correlation between number of calls and number of sales. P Value = 0.000 4. Determine the coefficient of determination. Interpret. It is more commonly known as R squared value. It measures how close the data points are to the line. The coefficient of determination .0722. 7.2% of the variations can be explained by knowing the number of calls made. SUMMARY OUTPUT Regression Statistics Multiple R 0. R Square 0. Adjusted R Square 0. Standard Error 4. Observations 100.
