An ANOVA procedure for a two-factor factorial experiment produced the following: a = 6, b = 2, r = 2, SSA = 1.05, SSB = 16.67, SSAB = .60, and SST = 94.52. What is the value of the test statistic for determining whether there is a main effect for factor A? a. 2.63 b. .02 c. The test statistic cannot be computed because SSE is not given. d. .03
