TABLE 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): 
₁ = 60.35, S₁ = 3.25, n₁ = 12
Sample II (financial planning): 
₂ = 58.20, S₂ = 2.48, n₂ = 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 Table 10-15, what is the critical value for testing whether there is evidence of a difference in the variances at the 5% level of significance?
