    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

    • B. 

      27.70 - 22.30 = 5.40

    • C. 

      27.70 / 22.30 = 1.24

    • D. 

      2.00(4.00) = 8.00

    • E. 

      37.00 - 13.00 = 24.00

  • 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.  Which of the following schemes should she use to do the simulation?
    • 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.
