The probability of a mean greater than 46, p(M > 46), in the previous problem having a sample of n = 324 was different than the probability of a mean greater than 46, p(M > 46), in the previous problem having a sample of n = 9. Why was that probability different? a) The distribution of sample means for the sample size n = 9 was much narrower with a smaller standard error, making a mean of 46 or higher much more likely. b) The distribution of sample means for the sample size n = 9 was much broader with a larger standard error, making a mean of 46 or higher much more likely. c) The distribution of sample means for the sample size n = 324 was much broader with a larger standard error, making a mean of 46 or higher much more likely
