d. Design utilization is 66%.
Explanation:
If the clinic gave flu shots to 330 seniors over ten hours, that's an average of 33 seniors per hour, comparing to the design capacity and effective capicity gives:
[tex] DesignPerc = \frac{33}{50} = 0.66\\ EffectivePerc= \frac{33}{44} = 0.75[/tex]
Therefore, Design utilization is 66% and Effective utilization is 75% so the answer is D.
