Please when answering the questions please put the number next to the answer so there is no confusion. (This is all the information they gave us and the paper said answer these questions)
Im so confused and really need help?
2. A population has a µ = 60 and σ = 10. A sampling distribution from that population, based on samples of n = 64, will have a M of ________ and a standard error of ___________.
3. Explain the relationship between distribution of sample means and normality-that is, under what circumstances is the distribution of sample means normal?
4. A sample of n = 81 scores is selected from a population with μ = 60 and σ = 9. On average, how much error is expected between the sample mean and the population mean?
5. A random sample of n = 25 scores is selected from a population. Based on this information alone, do I know that the distribution of samples means will be normal? Why or why not?
6. All samples of size n = 49 are selected from a population with μ = 40 with σ = 12. What is the average (mean) of the distribution of sample means? (this is not a trick, it is a very simple question!)
