The population mean and standard deviation are given below. Find the required probability and determine whether the Question list K given sample mean would be considered unusual. For a sample of n = 60, find the probability of a sample mean being less than 20.5 if u = 21 and o = 1.35. O Question 1 Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table. O Question 2 For a sample of n = 60, the probability of a sample mean being less than 20.5 if u = 21 and o = 1.35 is O Question 3 (Round to four decimal places as needed.) Would the given sample mean be considered unusual? O Question 4 The sample mean be considered unusual because it has a probability that is than 5%. Question 5 O Question 6The sample mean be considered unusual because it has a probability that is than 5%. would would notThe sample mean be considered unusual because it has a probability that is than 5%. less greater
