Example 5.5
Thickness of certain type of panels varies around mean of 18 cm with standard deviation of 3 mm.
Assume that thickness follows normal distribution, and determine:
a) Probability that thickness of a randomly chosen panel is less than 17.5 cm.
b) Probability that thickness of a randomly chosen panel exceeds 17.8 cm but does not exceed
18.3 cm.
c) Thickness that is exceeded by 5% of the panels.
d) Thickness that is not exceeded by 10% of the panels.
