    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. 

      Type of paint is a blocking factor.

    • C. 

      Gender is a blocking factor.

    • D. 

      This is a completely randomized design.

    • 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.

  • 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.
