A sample of n = 16 scores has a mean of M = 65 and an estimated standard error of 2 points.What is the sample variance? A)s² = 64 B)s² = 36 C)s² = 16 D)s² = 4

Question

Quizplus · Accepted Answer

The estimated standard error is calculated as the sample standard deviation (s) divided by the square root of the sample size (n). Given the standard error is 2, we have s/√16 = 2, which gives s = 8. Therefore, the sample variance s² = 8² = 64.
