- 2.Random variable X is normally distributed, with a mean of 25 and a standard deviation of 4. Which of the following is the approximate interquartile range for this distribution?
- A.
25.00 - 22.30 = 2.70

- 3.An experiment was designed to test the effects of three different types of paint on the durability of wooden toys. Because boys and girls tend to play differently with toys, a randomly selected group of children was divided into two groups based on gender. Which of the following statements about this experiment is true?
- A.
There are three types of paint and two gender groups, giving a total of six treatment combinations in this experiment.
- B.
Type of paint is a blocking factor.
- C.
Gender is a blocking factor.
- D.
This is a completely randomized design.
- E.
This is a matched pairs design in which one boy and one girl are matched by age to form a pair.
- 4.An insurance agent is successful in selling a life insurance policy to 20 percent of the customers she contacts. She decides to construct a simulation to estimate the mean number of customers she needs to contact before being able to sell a policy.

- A.
Assign numbers 0, 1 to successfully selling a policy to a customer and numbers 2, 3, 4 to failing to sell a policy to a customer.
- B.
Assign numbers 0, 1 to successfully selling a policy to a custome and numbers 2, 3, 4, 5, 6, 7, 8, 9 to failing to sell a policy to a customer.
- C.
Assign number 0 to successfully selling a policy to a customer and number 1 to failing to sell a policy to a customer.
- D.
Assign numbers 0, 1, 2, 3, 4 to successfully selling a policy to a customer and numbers 5, 6, 7, 8, 9, to failing to sell a policy to a customer.
- E.
Assign number 20 to successfully a policy to a customer and numbers 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 to failing to sell a policy to a customer.
- 5.Which of the following statements about any two events A and B is true?
- A.
P(A U B) = 0 implies events A and B are independent.
- B.
P(A U B) = 1 implies events A and B are mutually exclusive.
- C.
P(A ∩ B) = 0 implies events A and B are independent.
- D.
P(A ∩ B) = 0 implies events A and B are mutually exclusive.
- E.
P(A ∩ B) = P(A) - P(B) implies events A and B are equally likely events.
