3. A 2*6 factorial ANOVA was used to examine the effect of airline passengers' biological sex (Female or Male) and Class of Service they normally purchase with respect to their general attitudes toward the airline industry. Class of Service was based on Delta Air Lines (Basic Economy, Main Cabin, Delta Comfort +, First Class, Delta Premium Select, and Delta One), and attitudes were measured on a scale from 1 to 100 with higher scores indicating more positive attitudes. The author reported, "The results of data analysis showed that MMale = 90, MFemale = 60, F(1, 415) = 32.05, p < .001, and the effects of Class of Service and the corresponding interactions were small and not significant." What should the re- searcher do next?

a. Conclude that male passengers have more positive attitudes than female passengers.

b. Conduct a post hoc test to determine if the different seat classifications are significant.

c. Conclude that the results are inconclusive because the interactions were not significant.

d. Conclude that a computation mistake was made because F cannot be that large.
