#10: Use the Q10 dataframe. Consider three standard multiple linear regression models predicting Sales from both predictors and no interaction (i.e., ignoring the time series nature of the data): one with a linear trend, one with a quadratic trend, and one with a cubic trend. In the model with lowest of the three AICs, report the COEFFICENT ESTIMATE of the difference in average sales between First Quarter and Third Quarter. NOTE: To find the AIC of a model run AIC(ModelName).
