f. What is the probability that the sampling error (x) would be $1.50 or less? (Round z-value to 2 decimal places and final answer to 4 decimal places) A normal population has a mean of $89 and standard deviation of $8. You select random samples of 50 . a. Apply the central limit theorem to describe the sampling distribution of the sample mean with n=50. What condition is necessary to apply the central limit theorem
