A sample of n = 4 scores with SS = 48 has a variance of 16 and an estimated standard error of 2.

Quizplus · Accepted Answer

If the sample has a variance of 16, then the standard deviation is the square root of 16, which is 4. Since the estimated standard error is 2, the standard deviation of the population must be 2 times the standard error, which is 8. 
Using the formula for SS with a sample of 4 scores (SS = (n-1) * variance), we get:
SS = (4-1) * 16 = 48
Therefore, the statement is true.
