A researcher wants to know if there was a difference between urban and rural jurisdictions in the hiring of female police officers last year. In urban jurisdictions (N = 77), the mean number of females hired was 9.65 (s = 4.17). Police departments in nonurban areas (N = 84) hired an average of 6.80 females (s = 4.16). Using an alpha of .05, test the null hypothesis that there is no difference between the means.

What is the null hypothesis? What is the research hypothesis? What are the degrees of freedom? What is the critical value? Do you reject or fail to reject the null hypothesis? What does this mean?
