A botanist is conducting a two-factor experiment on seed germination. One factor is temperature, with two levels: cold storage and ambient temperature storage. The other factor is gibberelin treatment, which occurs at four different concentrations. Our botanist attempts this experiment on the cheap, with only one seed per treatment group (hey, maybe it's a coconut). If the ANOVA includes a test for the two-way interaction, how many degrees of freedom will our hero have for error? 3 0 4 7 1
