Occasionally, it has been the case that home prices and mortgage rates dropped so low that in a number of cities the monthly cost of owning a home was less expensive than renting. The following data show the average asking rent for 10 markets and the monthly mortgage on the median priced home (including taxes and insurance) for 10 cities where the average monthly mortgage payment was less than the average asking rent.

However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital satisfaction. (Data Source: National Center for Health Statistics.) A counseling psychologist sets out to look at the role of having children in relationship longevity. She decides to measure marital satisfaction in a group of couples with children and a group of childless couples. She chooses the Marital Satisfaction Inventory, because it refers to "partner" and "relationship" rather than "spouse" and "marriage," which makes it useful for research with both traditional and nontraditional couples. Higher scores on the Marital Satisfaction Inventory indicate greater satisfaction. Assume that these scores are normally distributed. 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…arrow_forward
