The Central Limit theorem would predict a sampling distribution of the mean with a mean of 4.5 and a standard deviation of 2.6/(5 = 1.16. These values are close to the values that we would expect. 12.5 If you had drawn 50 samples of size 15, the mean of the sampling distribution should still approximate the mean of the population, but the ...

Sampling Distribution of : As or the population is normally distributed, then , where . Thus, for some constants , where Z is the standard normal random variable. Example: What is the probability of the difference between the sample mean and the population mean will be less or equal to 500 as the sample size [solution]. Thus,

This is a t distribution with 10 degrees of freedom. As the degrees of freedom increase the sampling distribution is closer to a normal distribution. The degrees of freedom is found by taking your sample size –1. For example is your sample size is 15 your degrees of freedom would be 14 so you would look at the distribution for t = 14.

Sampling Distributions Review. 1. The Wechsler Adult Intelligence Scale (WAIS) is a common “IQ test” for adults. The distribution of WAIS scores for persons over 16 years of age is approximately normal with mean 100 and standard deviation 15. A. What is the probability that a randomly chosen individual has a WAIS score of 105 or higher?
