Questions: Using Durkheim's theory as a basis, a sociologist calculated the following suicide rates (number of suicides per 100,000 population, rounded to the nearest whole number) for 10 "high-anomie and 10 "low-anomie" metropolitan areas. Anomie (normlessness) was indicated by the presence of a large number of newcomers or transients in an area. The descriptive statistics of the two samples are: High-anomie areas: Mean = 21 and Variance = 12.8 Low-anomie areas: Mean = 13.7 and Variance = 8.41 Use a .05 alpha level to test the research hypothesis that high-anomie metropolitan areas have higher suicide rates than low-anomie areas, and answer the following questions:

a. Is this a one-tailed or two-tailed test?

b. Write the research and null hypothesis in Greek form (symbols).

c. What is the critical value of the test statistic?

d. What is the obtained value of the test statistic?

e. What decision about the null hypothesis does your test lead to?

f. What does this indicate about differences in suicide rates between high- and low-anomie areas?

g. Would your decision be different if you used an alpha level of .01? Explain.

h. If the researcher had originally hypothesized that the suicide rate would be different for high-anomie and low-anomie metropolitan areas, what would change in your hypothesis test? Would you be able to reject the null?
