Assume that the yield per acre for the new variety of yellow corn follows a Normal distribution with an unknown mean of u and a standard deviation of o= 10 bushels per acre. 23. If the average yield for these 25 plots is I = 150 bushels per acre, what is a 90% confidence interval for u? A) 150+ 0.784 B) 150+ 2.00 C) 150+ 3.29 D) 150+ 3.92
