We use standard normal table his Question: 2 pts 18 of 28

his Question: 2 pts 18 of 28 (27 complete) This Test: 60 pts possible Question Help The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n = 62, find the probability of a sample mean being less than 22.5 if u = 23 and o = 1.15. Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table. For a sample of n = 62, the probability of a sample mean being less than 22.5 if u = 23 and o = 1.15 is (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it has a probability that is than 5%. would not would Enter your answer in the answer box
