To test the efcacy of three different brands of fertilizer, you grow seedlings on each of the brands, plus a control with no fertilizer, for a total of four treatments. At the end of two months, you weigh each seedling. Here are the data, in grams: fertilizer A fertilizer B fertilizer C control 12 15 11 9 15 16 13 11 The question of interest was whether fertilizer affects plant growth. Before you even conducted the experiment, you planned to test fertilizer A against the control and fertilizer B against the control. In each case the hypothesis you will test is that the fertilizer compound is different than the control (i.e. each test is twosided). For each of the planned comparisons, what are the generic null and alternative hypotheses? A. H0: #fert = Mctmtrol HA: errt 7E I'mntrol B. H0: #fert :[ I-Lcontrol HA: errt = Mco-ntrol C. H0: #fe'.
