Question

Which of the following is not correct? For samples of any size N, the sampling distribution of the mean _____.

	a.	has a mean equal to the mean of the raw-score population.
	b.	is normally shaped, depending on the shape of the raw-score population and on the sample size, N.
	c.	has a standard deviation equal to the standard deviation of the raw-score population divided by N.
	d.	is a distribution of scores, each score of which is a sample mean of N scores.

Answer 1

Answer #1

Solution-:

Option (d) is a distribution of scores, each score of which is a sample mean of N scores is correct.

For samples of size 30 or more, the sample mean is approximately normally distributed with mean $\mu_{\bar{X}}=\mu$
