An experiment was conducted to assess the efficacy of spraying oats with Malathion (at 0.25 Ib/acre) to control the cereal leaf beetle. Twenty farms in southwest Manitoba were used for the study. Ten farms were assigned at random to the control group (no spray) and the other 10 fields were assigned to the treatment group (spray). At the conclusion of the experiment, the number of beetle larvae per square foot was measured at each farm, and a one-tailed test of significance was performed to determine if Malathion reduced the number of beetles. In which one of the following cases would a Type II error occur? (a) We do not conclude malathion is effective when in fact it was effective. (b) We conclude malathion is effective when in fact it is ineffective. (c) We conclude malathion is effective when in fact it is effective. (d) We do not conclude malathion is effective when in fact it is ineffective. (e) We conclude malathion is neither ineffective nor effective.
