In a study comparing four levels of Factor A and two levels of Factor B,with six observations in each cell,the SSE = 3456 and the SSA = 364.What is the value of the F statistic that is used to test for the main effect of Factor A?
A)1.05
B)1.26
C)1.40
D)4.21

The F statistic for the main effect of Factor A is calculated as SSA / (SSE / (a - 1) * (b - 1)), where a is the number of levels of Factor A and b is the number of levels of Factor B. In this case, a = 4, b = 2, SSA = 364, and SSE = 3456. Therefore, the F statistic is 364 / (3456 / (4 - 1) * (2 - 1)) = 1.40.
