###### Question:

A certain population has a mean of 500 and a standard deviation of 23. Many samples of size 41 are randomly selected and the means calculated.

(a) What value would you expect to find for the mean of all these sample means? (Give your answer correct to nearest whole number.)

(b) What value would you expect to find for the standard deviation of all these sample means? (Give your answer correct to two decimal places.)

(c) What shape would you expect the distribution of all these sample means to have? skewed right approximately normal skewed left uniform

You may need to use the appropriate table in Appendix B to answer this question.
