ASQ (American Society for Quality) routinely conducts a "salary survey" of
Quality professionals. Suppose it is interested in determining if the industries within
Which quality professionals work affect their salaries. They have salary data from
Random samples taken in three different industries: (1 = Consumer Goods, 2 = Financial,
3 = Health Care). Based on the partial ANOVA results shown below, the F statistic value
Is
One-way ANOVA: Salary versus Industry $$\begin{array} { l r r r r r }
\text { Source } & \text { DF } & \text { SS } & \text { MS } & \text { F } & \text { P } \
\text { Industry } & 2 & 23343 & 11671 & & \
\text { Error } & 27 & 16589 & 614 & \
\text { Total } & 29 & 39932 & &
\end{array}$$
A) F = 19.01
B) F = 1.407
C) F = 48.7
D) F = 0.499
E) None of the above

The F statistic is calculated by dividing the Mean Square for Industry (11671) by the Mean Square for Error (614), which gives F = 11671 / 614 = 19.01.
