We wаnt tо test the hypоthesis thаt the meаn yield оf a particular variety of corn is less than 150 bushels per acre. Therefore, we obtain the yields of a random sample of 20 corn fields in which this variety was planted. The average yield of the sample of fields was 140 bushels per acre with a standard deviation of 10 bushels per acre. We want to test: Ho: μ = 150 bushels/acre Ha: μ < 150 bushels/acre using a significance level (α) = 0.10. What is the critical value that defines the boundary of the rejection region in this problem?
