Suppose that a sample of 8 observations has a standard deviation of 2.50,then the sum of the squared deviations from the sample mean is 17.50.

Question

Quizplus · Accepted Answer

The sum of the squared deviations from the sample mean is calculated as (n-1) * s^2, where n is the sample size and s is the standard deviation. Using this formula, we can find that the sum of squared deviations is (8-1) * 2.50^2 = 43.75, which is not equal to 17.50. Therefore, the statement is false.
