As part of the study, a random sample of households in different Canadian cities was selected, and their monthly utility bills and number of bedrooms were recorded The data is provided in the dataset Utility Bills a] Plot the residuals against the tted values corresponding to the two-way ANDVA model for this analysis What two key model assumptions can be examined with this plot and do they appear to be warranted? b] Test the following hypothesis at the 1% signicance level; make sure you follow all the steps for hypothesis testing indicated in the instructions section. Use software to generate the corresponding two-way ANOVA table, but show any other computations. I Signicant interaction effect between number of bedrooms and city: . Signicant main effect of the number of bedrooms factor [if warranted); 0 Signicant main effect of the city factor [if warranted]. c] Create the corresponding interaction plot and explain if it shows interaction between number of bedrooms and city. is this consistent with your results for part b) above
