Please solve this in R with the code shown. Please do a, b, and c. 2. Continue with the Brand Preference dataset. a) Regress brand liking (Y) on sweetness (X2) using SLR model and obtain the residuals. b) Regress moisture content (X1) on sweetness (X2) using SLR model and obtain the residuals. c) Calculate the coefficient of simple correlation between the two sets of residuals and show that its square equals RY122..
