Consider the butterfat production (in pounds) for a cow during a 305-day milk production period following the birth of a calf. a sample of 12 cows on a farm in wisconsin has a mean of 712.25 and a variance of 29957.84. a sample of 16 cows on a farm in michigan has a mean of 705.44 and a variance of 20082.13. assume the distribution of butterfat production is normally distributed for both farms. find a 9596 confidence interval for the difference in average butterfat production, wisconsin michigan
a.30.154 < wisconsin - michigan < 163.788
b.-118.112 < wisconsin - michigan < 131.732
c.- 126.143 < wisconsin - michigan < 139.763
