the conditions itself have various null hypothesis.

13. The following data shows performance of four different types of firms marketing campaigns as a function of the age of the firm (old or young) and whether it was selling online or just in stores. Age stores Selling format old 9 8 7 3 2 1 young A B C D E F Online Unfortunately, six numbers (A,B,C,D,E,F) are not known Suppose you know that 1) The null hypothesis that there is no main effect of Selling format can be rejected at a 0.05 significance level and 2) The null hypothesis that there is no main effect of Age can be rejected at a 0.05 significance level and 3) The null hypothesis that there is no interaction effect cannot be rejected at a 0.05 significance level. In fact, the F ratio for the interaction effect equals zero. Given this, what could the six unknown numbers (A,B,C,D,E,F) be? How can you figure out what the numbers could be without computing the tests? Briefly explain your reasoning
