The number оf scrаtches оn а metаl sheet has the discrete unifоrm probability mass function p(x) = 1/4 for x = 0, 1, 2, 3.  You may recall from earlier material that the population mean of X is  = 1.5 scratches and the population standard deviation of X is  1.1180 scratches. Accept these values as fact even if you disagree. This question is part of a quiz or exam given at Arizona State University, copywritten by Dr. L. Chattin.  It may not be reproduced, posted or distributed without permission of Arizona State University and L. Chattin.  Thirty-six of these sheets are sampled.  To four decimal places, the probability that the sample mean is less than 1.680 scratches is _______.  Express your answer to 3 decimal places.   You must use the online calculator for this problem.  Zero credit will be earned if you do not, even if you get the correct answer: ti84.calc
