Extracted text: An experiment was conducted to assess the efficacy of spraying oats with Malathion (at 0.25 Ib/acre) to control the cereal leaf beetle. Two fields were used at each of 10 farms in southwest Manitoba. One field at each farm was assigned at random to either the control group (no spray) or the treatment group (5pray), and the second field was assigned to the other treatment. At the conclusion of the experiment, a plot on each farm was selected, the number of beetle larvae per square foot was measured, and a one-tailed test of significance was performed to determine if Malathion reduced the average number of beetles. The results are given below. Assurne conditions for the appropriate inference procedure have been met. In Control fields 6.20 1.30 Treatment fields Control Field- Treatment Field (Pairs) 4.76 1.44 2.49 15 1.26 Which of the following is the appropriate test statistic and interval for the P-value?
