This question has two parts.
Part 1) An insurance company surveys its
customers to determine the number of children under age 22 living
in each household.
What is the random variable for this survey?
a. The age of the children living in each household
b. The number of children under age 22 who are customers
c. The number of children under age 22 living in each household
d. Whether or not a child is a customer
Part 2) An insurance company surveys its
customers to determine the number of children under age 22 living
in each household.
Is the random variable discrete or continuous?
a. The random variable is discrete because it can assume an uncountably infinite number of values.
b. The random variable is discrete because it can only assume a finite number of values or an infinite sequence of values such as 0, 1, 2....
c. The random variable is continuous because it can only assume a finite number of values or an infinite sequence of values such as 0, 1, 2....
d. The random variable is continuous because it can assume an uncountably infinite number of values.

Question 4 (2 points) An automobile insurance company divides customers into three categories: good risks, medium risks, and poor risks. Assume that of a total of 12,573 customers, 6,524 are good risks, 1,190 are medium risks, and the rest are poor risks. As part of an audit, one customer is chosen at random. What is the probability that the customer is not a poor risk? Write only a number as your answer. Round to two decimal places (for example: 0.43)....

This question has two parts. Part 1) Assume that for an ad campaign to be successful, at least 76% of those seeing a television commercial must be able to recall the name of the company featured in the commercial one hour after viewing the commercial. Before distributing an ad campaign nationally, an advertising company plans to show the commercial to a random sample of 24 people. It will also show the same people two additional commercials for different products or...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
