A field biologist wants to test whether two species of mice have the same mean mass.She collects two random samples of10

mice from each species and measures their mass in grams. The results are shown in the following table. Assume that both species have a standard deviation of6.5

grams and that the mass for each speciesis normally distributed. Let the number of field mice be the first sample, and let the number of rock micebe the second sample.

She conducts a two-mean hypothesis testat the0.01

level of significance, to test ifthere is evidence that both species have the same mass.
