If the Mean of a Random Variable X Is 30 - Search Videos

A random variable X is not normally distributed. It has a mean of 53 and a standard deviation of 8. List the givens with correct symbols: Î¼ = 53, Ïƒ = 8.a) If you take a sample of size 11, what is the mean? Can you say what the shape of the sampling distribution for the sample is?Yes.Why or why not? Check all that apply:- The population is normal.- n is at least 30.- Ïƒ is known.b) For a sample of size 11, state the mean and the standard deviation of the sampling distribution of the sample mean
