Are nursing salaries in Tampa, Florida, lower than those in Dallas, Texas? As reported by the Tampa Tribune , salary data show staff nurses in Tampa earn less than staff nurses in Dallas. Suppose that in a follow-up study of 40 staff nurses in Tampa and 50 staff nurses in Dallas you obtain the following results. Tampa Dallas n 1 = 40 n 2 = 50 x ¯ 1 = $ 56 , 100 x ¯ 2 = $ 59 , 4 00 s 1 = $6000 s 2 = $7000 a. Formulate hypothesis so that, if the null hypothesis is rejected, we can conclude that salaries for staff nurses in Tampa are significantly lower than for those in Dallas. Use α = .05. b. What is the value of the test statistic? c. What is the p -value? d. What is your conclusion?
