That is Write A and start the answer for that question on the following line, and so on. Write R code to build a model with sales_qty as the response variable and price as the explanatory variable and to print the variances of the response variable, model values and the residuals. (4 points) Show the three variances -- you can copy the R output and paste it in. (1 point) What relationship do you expect to see between the three variances? (2 points) Do you see the expected results? (1 point) What proportion of the variability in the response variable does the model explain? (2 points) Show the code to extend the above to have advertising, product, and city in addition to price as explanatory variables. (2 points) SHow the three variances -- copy and paste the R output. (1 point) What proportion of variability does the new model explain? (1 point)
