Suppose nine items are sampled from a normally distributed population with a mean of 96 and a standard deviation of 22. The nine randomly sampled values are shown in the table. 115 82 72 115 106 65 112 48 121 Calculate the probability of getting a sample mean that is smaller than the mean for these nine sampled values. The probability that a sample mean is smaller than the mean for these nine values is (Round to four decimal places as needed.)
