Responses to stress are governed by the hypothalamus. Imagine you have two groups of subjects. The first shows signs of heart disease and the other does not. You want to determine whether the groups differ in terms of the weight of the hypothalamus. For the first group of subjects with no heart disease, the weights are
11.1,12.2,15.5,17.6,13.0,7.5,9.1,6.6,9.5,18.0,12.6.
For the other group with heart disease, the weights are 18.2,14.1,13.8,12.1,34.1,12.0,14.1,14.5,12.6,12.5,19.8,13.4,16.8,14.1,12.9.
Determine whether the groups differ based on Welch's test. Use α = .05
