Answer:

1.5

Step-by-step explanation:

The mean is the Middle number.

1 standard deviation in both sides of 7.5 makes it between 6 and 9.

What is the "common difference" in 6 to 7.5 and from 7.5 to 9?

$7.5-6=1.5$

and

$9-7.5=1.5$

So, we would say the standard deviation is 1.5

Answer choice A is right.
