13.11 Random numbers. If you ask a computer to generate “random numbers" between 0
and 5, you will get observations from a uniform distribution. Figure 13.12 shows the density
curve for a uniform distribution. This curve takes the constant value 0.2 between 0 and 5 and
is zero outside that range. Use this density curve to answer these questions.
a. Why is the total area under the curve equal to 1?
b. The curve is symmetric. What is the value of the mean and median?
c. What percentage of the observations lie between 4 and 5?
d. What percentage of the observations lie between 1.5 and 3?

Figure 13.12 The density curve of a uniform distribution, for Exercise 13.11.
Observations from this distribution are spread "at random" between 0 and 5.

According to the National Health Statistics report, the mean height of all adult (age 18 years and older) males in the United States in 69.4 inches. A random sample of 300 men aged 60 – 69 years old has a mean height of 69.0 inches, with a standard deviation of 2.65 inches. At α = 0.10, can we conclude that the population of older (aged 60 – 69 years old) men are shorter than the population of all men in the USA?
