Chapter 6: Q.2.1 (page 370)

A large auto dealership keeps track of sales and leases agreements made during each hour of the day. Let X= the number of cars sold and Y= the number of cars leased during the 铿乺st hour of business on a randomly selected Friday. Based on previous records, the probability distributions of Xand Yare as follows:

顿别铿乶别 T=X+Y.

Find and interpret 渭T.

Short Answer

Expert verified

From the given information, It is expected that 1.8of the cars would be sold or leased out in the first hour of business.

Step by step solution

01

Given Information

It is given in the question that,

渭X=1.1蟽X=0.943

渭Y=0.7蟽Y=0.64

蟿=蠂+纬

02

Explanation

The mean of T can be calculated as:

渭蟿=渭蠂+渭纬=1.1+0.7=1.8

Life insurance A life insurance company sells a term insurance policy to a21-year-old male that pays 100,000if the insured dies within the next 5years. The probability that a randomly chosen male will die each year can be found in mortality tables. The company collects a premium of 250each year as payment for the insurance. The amount Y that the company earns on this policy is 250per year, less the 100,000that it must pay if the insured dies. Here is a partially completed table that shows information about risk of mortality and the values of Y=profit earned by the company:

(a) Copy the table onto your paper. Fill in the missing values of Y.

(b) Find the missing probability. Show your work.

(c) Calculate the mean 渭Y. Interpret this value in context.
