25 A random sample is drawn from a normally distributed population with mean - 34 und standard deviation 0-22. a. Are the sampling distribution of the sample mean with a 42 and n=84 normally distributed? 4 Saints 0227 O Yes, both the sample means will have a normal distribution O No, both the sample means will not have a normal distribution. No, only the sample mean with n=42 will have a normal distribution No, only the sample mean with n=84 will have a normal distribution b. Calculate the probabilities that the sample mean is less than 34.7 for both sample sizes. (Round final answer to A decimal places.) Probability 42 84
