A feeding test is conducted on a herd of 25 dairy cows to compare two diets, A and B. A sample of 13 cows randomly selected from the herd are fed diet A and the remaining cows are fed with diet B. From observations made over a three-week period, the average daily milk production (in L) is recorded for each cow: Milk Yield (in L) Diet A 44 44 56 46 47 38 58 53 49 35 46 30 41 Diet B 35 47 55 29 40 39 32 41 42 57 51 39 Assume these tw samples come from independent normally distributed populations with equal variances. Is there any evidence to support the claim that there is a significant difference in true mean of the milk yields for the two diets?
