Textbook Question
Chapter 9.3, Problem 47E

Demand The daily demand x for a certain product (in hundreds of pounds) is a random variable with the probability density function

f ( x ) = 6 343 x ( 7 x ) ,          [ 0 , 7 ]

(a) Find the mean and standard deviation of the demand.

(b) Find the median of the demand.

(c) Find the probability that the demand is within one standard deviation of the mean.

The random variable X models the loss in thousands of dollars due to a fire in a commercial building. Its density function is f(x) = 0.005*(20-x) for 0 being less than or equal to x and x being less than or equal to 20 and f(x)= 0 otherwise. Given that a loss due to the fire exceeds $8000, find the probability the loss exceeds $16000.
The amount of time (in minutes) that a person spends reading the editorial page of the newspaper is a random variable with the density function f(x) = 1/72x, 0 ≤ x ≤ 12. Find the average time spent reading the editorial page.
The lifetime of a machine part has a continuous distribution on the interval (0,45) months with probability density function f, where f(x) is proportional to (4+x)-2. Find the probability that the lifetime of the machine part is less than 7 months.
