Responses to stress are governed by the hypothalamus. Imagine you have two groups of participants. 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 participants 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 = 0.05.
