Question 9 options:

	Distributions of sample means become approximately normally distributed when sample size is at least 30 for most populations.
	The distribution of the sample means become approximately normally distributed when sample size is at least 10 for symmetrical populations.
	Distributions of sample means become approximately normally distributed when sample size is at least 50 for highly skewed populations.
	Distributions of sample means are approximately normally distributed because the sample mean estimates the population mean.
	You can rely on statistical procedures for small sample sizes.
	Statistical procedures are robust to deviations from model assumptions.
	The distribution of the sample mean is always normally distributed.
