1. What is a sampling distribution?

2. When the mean of the sampling distribution ( x ) would be approximately normally distributed?

3. What is difference of the shape of the distribution of sample mean ( x ) and the shape of the distribution of x?

Hint: If there is a change of μ or σ, then it might affect the shape

True or False? The sampling distribution of the sample mean of a non-normally distributed population will also be normally distributed as long as the sample size is greater than 10. The sampling distribution of the sample mean of a normally distributed population will not be normally distributed if sample size is less than 30.
