To determine whether the five employees you choose will receive the bonus, you will need to compute a z score. For this, you will need to calculate the mean (average) number produced of the five employees you choose, and the average number produced by and the variance of the entire group. Using these, you can calculate your 'observed' z score. Once you have that, you can compare it to the 'critical' z score corresponding to .84 (for the 84%), and determine whether it falls outside the range, (if it does, that would indicate that they produce more than the other 84%, and should get their bonus). Remember, on your z table, the cutoff is the point below which that percentage of scores fall. So you need to look up an area of .84 (or .34 if you're just looking from the mean to z) in your z table to find that critical value.
