Question

For an IQ test, we know the population _ 5 100 and the _X 5 16. We are interested in creating the sampling distribution when N 5 64. (a) What does that sampling distribution of means show? (b) What is the shape of the distribution of IQ means and the mean of the distribution? (c) Calculate _X for this distribution. (d) What is your answer in part (c) called, and what does it indicate? (e) What is the relative frequency of sample means above 101.5?

Answer 1

Population mean = 100 and the standard deviation (SD) = 16, and N = 64?

Do you know where the = sign is?

Even so, we do not have data on the sample.
