Answer:

D

Step-by-step explanation:

The mean will be the very middle of the distribution, which is at 66. So we know that a and c are wrong.

The standard deviation is the distance between those bars, like 70 and 74. 74-70 = 4, so the standard deviation is probably around 4.

That means the answer is D.
The answer is d because that’s the only right answer
