Weights (kg) of poplar trees were obtained from trees planted in a rich and moist region. The trees were given different treatments identified in the accompanying table. Use a 0.05 significance 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? Click the icon to view the data table of the poplar weights. Determine the null and alternative hypotheses. Ho: H1 = H2 = H3 = H4 Poplar Weights (kg) X H1: At least one of the four population means is different from the others. Find the F test statistic.
