The Magnus Timber Company claims that it has replanted an average of (at least) 1500 trees per acre in areas that the company has harvested. Friends of the Forest, a conservation group, insists that the average is less than 1500 trees. You take a random sample of 75 acres that Magnus has harvested and find that the average number of replanted trees for the sampled acres is 1438. Is this sample result sufficient to reject the Magnus claim at the 5% significance level? Assume the population standard deviation is 340 trees. Report the p value for this sample result and explain what it means.
