In an agricultural study done to examine the impact of using a new mix of pesticides on the Canadian canola crop, a sample of 459 farms using the new pesticide mix and a sample of 295 farms using a conventional pesticide mix were randomly selected. The average gross revenue per acre for the sample of newmix farms was $ 181.90. The average gross revenue per acre for the sample of conventionalmix farms was $ 152.10 (source: canolacouncil. org). Construct a onetailed hypothesis test to determine if these sample results are sufficient to reject a null hypothesis that the average gross revenue for newmix farms is no greater than the average gross revenue for conventionalmix farms. Use a 5% significance level. Assume the population standard deviations are known: $ 83.40 for the population of newmix farms and $ 75.20 for the population of conventionalmix farms.
