Large trees growing near power lines can cause power failures during storms when their branches fall on the lines. Power companies spend a great deal of time and money trimming and removing trees to prevent this problem. Researchers are developing hormone and chemical treatments that will stunt or slow tree growth. If the treatment is too severe, however, the tree will die. In one series of laboratory experiments on 216 sycamore trees, 41 trees died. At a 5% significance level, is there enough evidence from this sample to conclude that the true proportion of sycamore trees that would die is more than 15%? The p-value from Minitab can be found below. Z-Value P-Value 1.64 0.0506
