explain the difference between creating a sampling distribution (i.e. plotting sample means or sample proportions in a probability distribution) vs. plotting individual data points.

explain why it makes sense that increasing the sample size should decrease the standard deviation in a normal distribution. Explain what this does to the overall shape of the normal curve

Can a normal approximation be used for a sampling distribution of sample means from a population with μ=43 and σ=8, when n=36? Answer TablesKeypad Yes, because the mean is greater than 30. No, because the sample size is more than 30. Yes, because the sample size is at least 30. No, because the standard deviation is too small.
