The data below are yields for two different types of com 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 a 95% confidence interval estimate of the difference between type 1 and type 2 yields. What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed? Type 1 21 15 2013 2201 2541 2182 1929 2189 1560 Type 2 2002 1929 2086 2471 2166 1949 2102 1489 In this example, jo is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the type 1 seed yield minus the type 2 seed yield. The 95% confidence interval is (Round to two decimal places as needed.)
