The Damon family owns a large grape vineyard in western New York along Lake Erie. The grapevines must be sprayed at the beginning of the growing season to protect against various insects and diseases. Two new Insecticides have just been marketed: Pernod 5 and Action. To test their effectiveness, three long rows were selected and sprayed with Pernod 5, and three others were sprayed with Action, When the grapes ripened. 430 of the vines treated with Pernod 5 were checked for Infestation. Likewise, a sample of 390 vines sprayed with Action were checked. The results are; Number of vines Checked (sample Insecticide size) Number of Infested Vines Pernod 5 439 24 Action 390 At the 0.05 significance level. can we conclude that there is a difference in the proportion of vines Infested using Pernod 5 as opposed to Action? Hint For the calculations, assume the Pernod 5 as the first sample. s. State the decision rule. (Negative amounts should be Indicated by a minus sign. Do not round the Intermediate values.
