Question

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 22.2 it-22 and 1.24 Click the icon to view page 1 of the standard normal table. EIB Click the icon to view page 2 of the standard normal table 124 is For a sample of n=62, the probability of a sample mean being less than 22 21 - 22 and (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% stend tesou access uccess Enter your answer in the answer box a Libre 11:59pm

Answer 1

9. : 62, u = 22,6 | 24 za V62(X-22) √52.0.2 PXL 22,2)=P(22 10.24) - P( Z41.27) 10.8980 The sample mean can't be considered unusual because it has prob that is more than 5%
