   Question

   We analyze whether students’ performance differs between 3 subjects: literature, essay writing and mathematics (they appear in this order in the dataset). In addition, we examine whether any differences between the 3 subjects vary between male and female schoolchildren. Therefore, we use a Mixed Design ANOVA. The output of this analysis is shown below. Female is coded as 0: male, 1: female.
   By what F value can we test whether the differences in performance between math and the other 2 subjects combined writing vary between male and female school students?
