Decides

Decide by calculation how many candidates out of a total of 1000 candidates for the position of CEO meet the eligibility requirements for the desired performance of this top management position with at least 67% probability - provided, of course, that the competency for the position of CEO is normally distributed among candidates, i.e., following normal distribution!

Final Answer:

n =  200

Step-by-step explanation:

$$\begin{gathered} \mu =500 \\ \sigma =100 \\ {n}_1=\mu +1\cdot \sigma =500+1\cdot 100=600 \\ {n}_2=\mu -1\cdot \sigma =500-1\cdot 100=400 \\ n=n_1-n_2=600-400=200 \end{gathered}$$
