You may need to use the appropriate technology to answer this question. Suppose a certain state university's college of business obtained the following results on the salaries of a recent graduating class: Finance Majors Business Analytics Majors Ho: n₁ = 120 X₁ = $48,437 $₁ = $19,000 x₂ = $55,417 $₂ = $10,000 (a) Formulate hypotheses so that, if the null hypothesis is rejected, we can conclude that salaries for Finance majors are significantly lower than the salaries of Business Analytics majors. Use a = 0.05. (Le population mean salary for Finance majors, and let #₂ = the population mean salary for Business Analytics majors. Enter != for as needed.) H₂: n₂ = 30 (b) What is the value of the test statistic? (Use #₁ - H₂. Round your answer to three decimal places.) (c) What is the p-value? (Round your answer to four decimal places.) p-value= (d) What is your conclusion? O Reject H. We cannot conclude that salaries for Finance majors are significantly lower than the salaries of Business Analytics majors. Do not reject H. We cannot conclude that salaries for Finance majors are significantly lower than the salaries of Business Analytics majors. O Do not reject Ho. We can conclude that salaries for Finance majors are significantly lower than the salaries of Business Analytics majors. Reject H. We can conclude that salaries for Finance majors are significantly lower than the salaries of Business Analytics majors.
