The cruise. csv file on Canvas contains data on 158 cruise ships in operation worldwide as of 2013. We will use Capacity(passenger capacity in 100s) as the response andLength(in 100s of feet) and Crew (in 100s) as predictors. Download the data and do the following. a. Fit the model with both predictors and their interaction. Perform a test on the significance of the interaction’s coefficient, including a test statistic and p-value.
b. Interpret the interaction’s estimated effect by finishing the following sentence: For every additional hundred feet of length of a ship, the mean passenger capacity increases by when there are 4 (hundred) crew, by when there are 8 (hundred) crew, and by when there are 12 (hundred) crew.
