You may need to use the appropriate technology to answer this question. Are nursing salaries in City A lower than those in City B? As reported by a newspaper, salary data show staff nurses in City A earn less than staff nurses in City B. Suppose that in a follow-up study of 40 staff nurses in City A and 50 staff nurses in City B you obtain the following results. City A City B ու = 40 n₂ = 50 X1 $56,400 X2 $59,500 = $1 = $6,000 $₂ = $7,000 (a) Formulate hypotheses so that, if the null hypothesis is rejected, we can conclude that salaries for staff nurses in City A are significantly lower than for those in City B. Use α = 0.05. Ho: M₁ - μ₂> 0 = 0 о Ha: 41-420 Hoμ1 - μ20 Hai H₂-12=0 Ho₂-14220 < 0 о (b) What is the value of the test statistic? (Round your answer to three decimal places.) -2.261 (c) What is the p-value? (Round your answer to four decimal places.) p-value = 125.67 ×
