Question:

The thickness of a laminated covering for a wood surface is normally distributed with a mean of 5 millimeters and a standard deviation of 0.2 millimeter.

(a) What is the probability that a covering thickness is greater than 5.5 millimeters?

(b) If the specifications require the thickness to be between 4.5 and 5.5 millimeters, what proportion of coverings do not meet specifications?

(c) The covering thickness of 95% of samples is below what value?
