Question

Quizplus · Accepted Answer

The distribution of values taken by the average exercising time in all possible samples of size 10 is called the sampling distribution of the average exercising time. This is because it represents the distribution of sample means. The probability distribution of exercising times refers to the distribution of individual exercising times, not the distribution of sample means. Variance of the exercising time values refers to how spread out the individual exercising times are, not the distribution of sample means. Population parameter refers to a characteristic of the entire population, not the distribution of sample means.
