An agricultural researcher plants 25 plots with a new variety of yellow corn. Assume that the yield per acre for the new variety of yellow corn follows a normal distribution with unknown mean µ and standard deviation o= 10 bushels per acre. If the average yield for these 25 plots is X = 150 bushels per acre. What is a 90% confidence interval for u?
