2. Create a dummy variable from 'endcap' and summarize your observations from the descriptive statistics of the variables. 3. Run correlations on the following variables: SALE, PRICE, SALEREP, ENDCAP, DEMO, DEMO13, DEMO45. Summarize your findings. 4. (Use Tableau: Submit a Tableau two file) Draw two graphs that provide useful insights. Explain your findings ()- (Q5 - 9) Run the following regression model. Sales = b. + b, *Price + b, *Endcap + b,*Salerep + b,*Demo + b*Demo13 + b*Demo45 + e 5. Report R-squared and adjusted R-squared. 6. Report the regression coefficients and p-values. Are the coefficients statistically significant? 7. Interpret the coefficients of Salesrep, Demo, and Endcap dummies
