Quizplus · Accepted Answer

The formula for standard error is:

standard error = standard deviation / square root of sample size

In this case, we know that the standard error is 6 and the sample size is 9. Solving for the standard deviation, we get:

6 = standard deviation / √9

6 = standard deviation/3

Standard deviation = 6 * 3 = 18

Therefore, the correct answer is B) 18.
