The data below are yields for two different types of corn seedthat were used on adjacent plots of land. Assume that the data aresimple random samples and that the differences have a distributionthat is approximately normal. Construct a? 95% confidence intervalestimate of the difference between type 1 and type 2 yields. Whatdoes the confidence interval suggest about farmer? Joe's claim thattype 1 seed is better than type 2? seed? Type 1 1988 2014 2190 24782208 1983 2258 1504 Type 2 2012 1919 2099 2437 2167 1911 2179 1444In this? example, mu Subscript d is the mean value of thedifferences d for the population of all pairs of? data, where eachindividual difference d is defined as the type 1 seed yield minusthe type 2 seed yield. The? 95% confidence interval is 24.66 lessthanmu Subscript dless than89.09 . ?(Round to two decimal placesas? needed.) What does the confidence interval suggest aboutfarmer? Joe's claim that type 1 seed is better than type 2? seed?A. Because the confidence interval only includes positive valuesand does not include ?zero, there is sufficient evidence to supportfarmer? Joe's claim. This is the correct answer. B. Because theconfidence interval includes ?zero, there is sufficient evidence tosupport farmer? Joe's claim. C. Because the confidence intervalonly includes positive values and does not include ?zero, there isnot sufficient evidence to support farmer? Joe's claim. Your answeris not correct. D. Because the confidence interval includes ?zero,there is not sufficient evidence to support farmer? Joe'sclaim.
