Question 1011520: An industrial engineer intends to use the mean of a random
sample of size n = 150 to estimate the average
mechanical aptitude (as measured by a certain test) of
assembly line workers in a large industry. If on the b
basis of experience, the engineer can assume that α =
6.2 for such data, what can be assert with probability
0.99 about the maximum size of his error?

-----------
ME = 2.5758*6.2/sqrt(150) = 1.304
