Suppose that a simple random sample of n = 6 individuals is obtained from a population that is skewed right with mean u = 44 and standard deviation o =2. (a) The shape of the sampling distribution of the sample mean is approximately normal. Is this true or false? (b) What is the mean of the sampling distribution of the sample mean? (c) What is the standard deviation of the sampling distribution of the sample mean? (a) Choose the correct...
