[You may find it useful to reference the z table.) 12.5 points a. Is the sampling distribution of the sample mean with n = 18 and n = 47 normally distributed? (Round the standard error to 3 decimal places.) n Expected Value Standard Error 18 OF HIT b. Can you conclude that the sampling distribution of the sample mean is normally distributed for both sample sizes? O Yes, both the sample means will have a normal distribution. No, both the sample means will not have a normal distribution O No, only the sample mean with 11 = 18 will have a normal clistribution. No, only the sample mean with 1 = 47 will have a normal distribution. Heerences c. If the sampling clistribution of the sample mean is normally distributed with n=18, then calculate the probability that the sample mean falls between 74 and 77. (if appropriate, round final answer to 4 decimal places.) We cannot assume that the sampling distribution of the sample mean is normally distributed. O We can assume that the sampling distribution of the sample mean is normally clistributed and the probability that the sample mean falls between 74 and 77 is Prostility 0.4995 d. If the sampling distribution of the sample mean is normally distributed with = 47, then calculate the probability that the sample mean falls between 74 and 77 (If appropriate, round final answer to 4 decimal places.) O we cannot assume that the sampling distribution of the sample mean is normally distributed.
