Question
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 95% confidence interval for the difference in average butterfat production, Wiscon sin Michigan - O-126.143 μWiscon sin 30.154 Wiscon sin O-130.617 - - < μWiscon sin -120.958 < Wiscon sin - Michigan 163.788 - Michigan < 139.763 - Michigan < 122.841 Michigan < 134.578

The blood volumes in milliliters is collected for two samples of males, one from males who are paraplegic and participate in vigorous physical activities and another from males who are able-bodied and participate in normal activities. Assume the variances blood volume measurements have normal distributions for both populations of males with a common variance. The sample of 7 males who are paraplegic and participate in vigorous physical activities had a mean blood volume of 1511.7 with a variance of 49669.9. The sample of 10 males who are able-bodied and participate in normal activities had a mean blood volume of 1118.40 with a variance of 15297.6. Find a 99% confidence interval for the difference in mean blood volume, paraplegic - Mable bodied. 145.784 paraplegic Hable bodied < 640.816 Mable bodied < 704.666 228.682 paraplegic Mable bodied < 557.185 177.028 < paraplegic Hable bodied < 609.572 152.333<paraplegic - -
