7. The standard deviation of the mean for the sampling distribution of random samples of size n-36 from a large (or infinite) population is 2. How large must the sample size be to decrease the standard deviation to 1.2?
When samples of size n are drawn from a population, then the sampling distribution of the sample mean X̄ is approximately normal, provided that n is reasonably large. a. True b. False The interval estimate 18.5±2.5 is developed for a population mean in which the sample standard deviation s is 7.5. Had s equaled 15 instead, the interval estimate would be 37±5.0. a. True b. False

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...
