A 500-page book contains 250 sheets of paper. The thickness of the paper used to manufacture the book has a mean of 0.08 mm and a standard deviation of 0.01 mm.
a. What is the probability that a randomly chosen book is more than 20.2 mm thick (not including the covers)?
b. What is the 10th percentile of book thicknesses?
c. Someone wants to know the probability that a randomly chosen page is more than 0.1 mm thick. Is enough information given to compute this probability? If so, compute the probability. If not, explain why not.
