A sample of 39 couples with children scored an average of 51.1 with a sample standard deviation of 9.2 on the Marital Satisfaction Inventory. A sample of 31 childless couples scored an average of 45.2 with a sample standard deviation of 12.1. Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you call the sample of couples with children sample 1 and the sample of childless couples sample 2.
