The data below are yields for two different types of corn seed that were used on adjacent plots of land. Assume that the data are simple random samples and that the differences have a distribution that is approximately normal. Construct a95% confidence interval estimate of the difference between type 1 and type 2 yields. What does the confidence interval suggest about farmerJoe's claim that type 1 seed is better than type 2seed?
