2. A Suay vиas maae to сотраre tпе costs oj supporing a јатпу Jor a ye In aifferent foreign cities. Suppose an executive wants to determine whether there is any difference in the average annual cost of supporting her family of four in Toronto and Mexico City. She uses the following data, randomly gathered from 11 families in each city, and a level of significance of 0.05 to test this difference. She assumes that the annual cost is normally distributed. The data that she used is detailed below. Assume the pop variances are equal. (TTEST) Toronto Mexico $65.000. $64,000 $66,000 $64,900 $62,000 $60,500 $69.000 $64,500 $67,500 $64,500 $66,700 $68,000

2. A study was made to compare the costs of supporting a family of four Americans for a year in different foreign cities. Suppose an executive wants to determine whether there is any difference in the average annual cost of supporting her family of four in Toronto and Mexico City. She uses the following data, randomly gathered from 11 families in each city, and a level of significance of 0.05 to test this difference. She assumes that the annual cost is normally distributed. The data that she used is detailed below. Assume the pop variances are equal. (TTEST) Toronto Mexico $69.000. $64,500 $67,500 $64,500 $66,700 $68,000 $65,000 $69,000 $71,000 $68,500 $67,500 $65.000. $64,000 $66,000 $64,900 $62,000 $60,500 $62,500 $63,000 $64,500 $63,500 $62,400
