Essay

According to an advertisement, a strain of soybeans planted on soil prepared with a specified fertilizer treatment has a mean yield of 107 bushels per acre. Twenty farmers who belong to a cooperative plant the soybeans in soil prepared as specified. Each uses a 40-acre plot and records the mean yield per acre. The mean and variance for the sample of the 20 farms are $\bar { x } = 92 \text { and } s ^ { 2 } = 18,000$ . Find the rejection region used for determining if the mean yield for the soybeans is not equal to 107 bushels per acre. Use α = .05.
