Astudy was conducted to compare the costs of supporting a family of four Canadians for a year in different foreign cities. The lifestyle of living in Canada on an annual income of $75,000 was the standard against which living in foreign cities was compared. A comparable living standard in Perth, Australia, and Mexico City was attained for about $64,000. Suppose an executive wants to determine whether there is any difference in the average annual cost of supporting her family of four in the manner to which they are accustomed in Perth and Mexico City. She uses the following data, randomly gathered from 11 families in each city, and an alpha of 0.01 to test this difference. She assumes the annual cost is normally distributed and the population variances are equal. What does the executive find? Perth, Mexico City Australia $69,300 $64,000 63,600 64,000 67,500 65,600 63,600 64,900 66,700 62,000 68,000 60,500 65,000 63,100 69,300 63,000 71,000 64,500 68,500 63,500 67,500 61,400
