1. 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	Non-coastal areas
n1 = 150	n2 =175
X1 bar = 39.3 years	X2 bar = 35.4 years
s1 = 16.8 years	s2 = 15.2 years

Test the hypothesis of no difference between the two population means. Use = 0.05. What is the value of the test statistic? Given that the p-value is 0.02, what is your conclusion?
