2. An experiment was conducted to compare five treatments for reducing fever. Thirty-five patients were randomly assigned into five treatment groups. The patients' temperatures were taken two hours after receiving the treatment, and are given below. We will test the claim that there is no difference in mean body temperature among each of the five treatment groups using a 5% significance level.

device that shakes the cherry tree, causing the cherries to fall
onto plastic tarps that funnel the cherries into bins. Ms. Wright
