A rancher tried Feed A on 25 cattle and Feed B on 21 cattle. Themean weight of cattle given Feed A was found to be 1,400 poundswith a standard deviation of 220 pounds. The mean weight of thecattle given Feed B was found to be 1,350 pounds with a standarddeviation of 170 pounds.
Part 1 of 3 Find a 95% confidence interval for the difference,calculated as (Feed A) − (Feed B), in the true mean weights ofcattle given the two feeds as well as a confidence level statement.Assume that weights of cattle on these feeds are approximatelynormally distributed. (Use a table or technology. Round youranswers to three decimal places.)
Does the confidence interval support the belief that Feed Aresults in higher cattle weights than Feed B? Why or why not?
