The cdf of checkout duration X as described in Exercise 1 is

Use this to compute the following:

a. P(X ≤ 1)
b. P(.5 ≤ X ≤ 1)
c. P(X > .5)
d. The median checkout duration

e. F′(x) to obtain the density function ƒ(x)

Data From Exercises 1

Let X denote the amount of time for which a book on 2-h reserve at a college library is checked out by a randomly selected student and suppose that X has density function
