Question 956166: The number of flaws per sheet of plywood has a mean of 3 and a standard deviation of 0.9.
If possible, find the probability that a randomly chosen sheet of plywood has 3 or more flaws. If impossible, tell why
Is this impossible because n must be greater than 30 or the distribution must be known
PLEASE, PLEASE HELP Answer by Edwin McCravy(20060) (Show Source):
This is a trick question.
Since the mean is 3, that means that half of the sheets of plywood in the world
have 3 or more flaws and the other half have 3 or fewer flaws. So the probability
is 50% or 0.5. The distribution and the standard deviation do not matter. The
standard deviation was given just to throw you off.
