Carry out a test of the null hypothesis that seedlings in the unthinned regions grow on average 2 cm higher than seedlings in the thinned region against the two-sided alternative, using = 0.05. State the hypotheses symbolically, compute the test statistic, compute the p-value, make a reject or not-reject decision, and state a conclusion in the context of the problem.
