Question Help The data below are yields for two difleront types of con seed that were used on adjacent plots of land Asume that the data are simple random samples and that the dileronces have a distibuion that is approximately nomal Construct a 95 % confidence interval estimate of the diference betweon type 1 and type 2 yiolds What does Be confidonce interval uggest about famer Joe's caim that type 1 seed is beter than type 2 seed? Type 1 Type 2 20/0 2012 2045 1987 2002 2031 2399 2402 2090 2119 1943 1912 21/5 2119 1452 1429 In this example, P the mean value of the diferences d for the population of all pairs of data, wheee each individual differonced is defined as the type 1 seed yiekd mis the type 2 seed yield The 95% confidence inderval is 3.62 57 63 (Round to two decimal places as needed) What does the confidence intorval suggest about farmer Joe's claim that type 1 seed is better han type 2 seed OA Because the confidence interval includes zero, there is sufficilent evidence to support lamer Joe's claim OB. Because the confidence interval only includes positive values and does not include zero, there is not suficiont evidence to support farmer Joe's claim OC. Because the confidence interval only Includes positive values and does not include zere, thore is sufficiont evidence to support farmer Joe's daim OD.
