Twenty laboratory mice were randomly divided into two groups of10. Each group was fed according to a prescribed diet. At the endof 3 weeks, the weight gained by each animal was recorded. Do thedata in the following table justify the conclusion that the meanweight gained on diet B was greater than the mean weight gained ondiet A, at the ? = 0.05 level of significance? Assume normality.(Use Diet B - Diet A.)
Diet A 5 13 9 8 10 14 5 8 7 5
Diet B 15 10 11 13 16 11 20 11 10 13
(a) Find t. (Give your answer correct to two decimalplaces.)
(ii) Find the p-value. (Give your answer correct to four decimalplaces.)
Is there a way to do this problem on a TI-84 Plus calculator? Ifso can you please break down the steps in getting the answers onthe calculator? Thank you!
