This problem uses the weights of poplar trees for Year 1 and Site 1. If we use the weights for Year 2 and site 1, the analysis of variance results are shown above.
Assume we want to use a 0.05 significance level in testing the null hypothesis that the four treatments result in weights with the same population mean.
See attached file for full problem description.
a. What is the null hypothesis?
H0: There is no significant difference in the mean of four treatments
b. What is the alternative hypothesis?
H1: There is ...
This problem uses the weights of poplar trees for Year 1 and Site 1, then uses the weights for Year 2 and site 1 when the analysis of variance is completed.
