Find F

I6 Weights (kg) of poplar trees were obtained from trees planted in a rich and moist region. The trees were given different treatments identied in the accompanying table. Use a 0.05 signicance level to test the claim that the four treatment categories yield poplar trees with the same mean weight. Is there a treatment that appears to be most effective? g Click the icon to view the data table of the poplar weights. Determine the null and attemative hypotheses. ' Ho= P1 = P2 = P3\" H4 H1: At least one of the four population means is different from the others. Find the F test statistic. F = (Round to four decimal places as needed.)
