Question 172165: An industrial process that makes 3-foot sections of plastic pipe produces pipe with an average inside diameter of 1 inch and a SD of 0.05 inch. If you randomly select one piece of pipe what is the probability that its inside diameter will exceed 1.02 inch assuming the population is normal.

An industrial process that makes 3-foot sections of plastic pipe produces pipe with an average inside diameter of 1 inch and a SD of 0.05 inch. If you randomly select one piece of pipe what is the probability that its inside diameter will exceed 1.02 inch assuming the population is normal.
-------------------
z(1.02) = (1.02-1)/0.05 = 0.4
So P(x>1.02) = P(z>0.4)
Use your z-chart to determin the probability that z>0.4
----------
Ans: 0.3446
