I am seeking help on the bullet points starting with "Find the test statistic..." and ending with "Explain what the p-value represents. Here is the scenario and the pertinent data. A biologist believes that the population of rats in a subway tunnel may actually be a new subspecies, because they appear to be heavier on average than those above ground. This is the statistics gathered with the weight in ounces:

Rats in tunnel:        Rats above ground:

n = 97                     n = 76

Mean1 = 29.1.        Mean2 = 28.3

S.Dev = 2.7           S.Dev = 2.4

Does she have enough evidence to conclude that the subway rats are heavier on average? What is the relationship between this test and the confidence intervals for the two means?
