A study was undertaken to measure and compare sexist attitudes of students at various types of colleges. Random samples of 10 undergraduate seniors of each sex were selected from each of three types of colleges. A questionnaire was then administered to each student, from which a score for "degree of sexism"€”defined as the extent to which a student considered males and females to have different life roles€”was determined (the higher the score, the more sexist the attitude). The resulting data ate given in the following table.

a. Form the table of cell means, and interpret the results obtained (see the accompanying computer printout).
b. Using the computer output, calculate the F statistics corresponding to a model with both factors fixed.
c. Discuss the analysis of the data for this fixed-effects model case.
