21 because it is being multiplied
Answer:
6/11
Step-by-step explanation:
there are 12 gold clips out of 22, so 12/22 and divide both sides by two to simplify.
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

Therefore, our variance is 225.
The answer is the first answer choice
