a. 13
b. 24
c. 576
d. 28,461

Answer 1

The standard deviation of the sample with a variance of 576 is 24. Hence the correct answer is option B

Step-by-step explanation:

The standard deviation is the square root of the variance, so to find the standard deviation of the sample, we take the square root of 576.
The square root of 576 is 24, so the correct answer is 24.

Hence the correct answer is option B
