Data were collected on residents living in the coastal communities as well as on residents living in non-coastal areas throughout the United States (USA Today, July 21, 2000). Assume that the following sample results were obtained on the ages of individuals in the two populations: = Coastal areas ni 150 x1 = 39.3 years S1 = 16.8 years Non-coastal areas n2 = 175 X2 = 35.4 years S1 = 15.2 years = Test the hypothesis of no difference between the two population means. Use a = 0.05. What is the value of the test statistic? Given that the p-value is 0.02, what is your conclusion? (10)
