Question

drawn from a population with mean μ-52 and standard deviation σ= 4.3. Mou may find it useful to reference A random sample the z table.] a. Is the sampling distribution of the sample mean with n-13 and n# 39 normally distributed? ○Yes, both the sample means will have a normal distribution. O No, both the sample means will not have a normal distribution. O No, only the sample mean with n 13 will have a normal distribution. O No, only the sample mean with n= 39 will have a normal distribution. b. Calculate the probability that the sample mean falls between 52 and 54 for n= 39. (Round intermediate calculations to at least 4 decimal places, "z value to 2 decimal places, and final answer to 4 decimal places.) Probability
