Using the same highway mileage dataset as in questions 18-21, we are interested in a regression model to predict hwy mpg from type of drive. to prepare for this, we first do the 1-way anova shown above. assume that the conditions for a valid 1-way anova are satisfied. one-way anova: hwy mpg versus driveanalysis of variancesource df adj ss adj ms f-value p-valuedrive 2 4542 2270.79 127.59 0.000error 306 5446 17.80total 308 9988tukey pairwise comparisonsgrouping information using the tukey method and 95% confidencedrive n mean groupingf 167 33.353 aa 61 25.787 br 81 25.568 bmeans that do not share a letter are significantly different. from just the p-value of this anova we can conclude that, at any typical α level:
