In a study of cereal leaf beetle damage on oats, researchers measured the number of beetle larvae per stem in small plots of oats after randomly applying one of two treatments: no pesticide and Malathion at a rate of 0.25 pounds per acre. The data are summarized below. treatment n x ? no pesticide 13 3.47 1.21 malathion 14 2.36 .52 Conduct a 2-sample z-test at α = .05 to determine if there is sufficient evidence to conclude that the mean number of larvae differs when Malathion is applied.
