Question

Question 2 A sample has a mean Xbar = 35 and standard deviation of s= 10. Would a score of 40 be considered an outlier (extreme value) in this sample? Write an explanation of not more than 3 lines to support your answer

Answer 1

as we know that a absolute z score of more then 3 is considered to be an outlier

for z score=(X-mean)/std deviation =(40-35)/10 =0.5

as the z value does not fall in outlier region l it should not be considered to be an outlier.
