10 If the random variable X comes from a normal distribution

10. If the random variable X comes from a normal distribution then the sampling distribution is approximately variable X does not come from a normal distribution then the sampling distribution is approximately If the random , if n is 30 or more due to the Central Limit Theorem. (10 points)

Solution

normal, normal

Also: it should be \"Exactly normal\" instead of \"approximately normal\" in first case when X is normal.
