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
n1 = 140	n2 = 30
x1 = $48,137	x2 = $55,417
s1 = $19,000	s2 = $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 = 0.05. (Let ₁ = the population mean salary for Finance majors, and let ₂ = the population mean salary for Business Analytics majors. Enter != for as needed.)
