For assignment, please work out below based on the OJ Data. Thanks!
1. Make a scatter plot for each of the following, putting price on the horizontal axis. You may use price/oz.
Price SKU 1 vs Unit Sales SKU 1
Price SKU 2 vs Unit Sales SKU 2
Price SKU 3 vs Unit Sales SKU 3
Price SKU 4 vs Unit Sales SKU 4
Price SKU 5 vs Unit Sales SKU 5
2. Add a linear trend line to each plot from question 1. Add the regression equation and R squared.
3. For each SKU, make a prediction about the effects of increasing price by $0.01 on sales. Does this result make sense? Which result are you most confident in?
