Question 610142: A diameters of bolts produced by a certain machine ae normally distributed with a mean of 0.30 inches and a standard deviatin of 0.01 inches. What percentage of bolts will have a diameter greater than 0.32 inches?
I have: 0.32-0.30/0.01=2

The z-score is:
0.32-0.30/0.01=2
.
Looking at the z-score table we find:
z-score of 2 = 0.9772
So, bolts larger than this would be:
1-0.9772 = 0.0228
Or
2% of bolts would be larger
