SCENARIO 10-15
The table below presents the summary statistics for the starting annual salaries (in thousands of dollars) for individuals entering the public accounting and financial planning professions.
Sample I (public accounting) : $\bar { X } _ { 1 } = 60.35 , S _ { 1 } = 3.25 , n _ { 1 } = 12$
Sample II (financial planning) : $\bar { X } _ { 2 } = 58.20 , S _ { 2 } = 2.48 , n _ { 2 } = 14$ Test whether the mean starting annual salaries for individuals entering the public accounting professions is higher than that of financial planning assuming that the two population variances are the same.
-Referring to Scenario 10-15, which of the following represents the relevant hypotheses tested?

A) $H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } \geq 0 \text { versus } H _ { 1 } : \mu _ { 1 } - \mu _ { 2 } < 0$
B) $H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } \leq 0 \text { versus } H _ { 1 } : \mu _ { 1 } - \mu _ { 2 } > 0$
C) $H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 0 \text { versus } H _ { 1 } : \mu _ { 1 } - \mu _ { 2 } \neq 0$
D) $H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } \neq 0 \text { versus } H _ { 1 } : \mu _ { 1 } - \mu _ { 2 } = 0$
