143 The Normal Distribution and Other Continuous Distributions 4. For some positive value of Z , the probability that a standardized normal variable is between 0 and Z is 0.3770. The value of Z is 5. For some value of Z , the probability that a standardized normal variable is below Z is 0.2090. The value of Z is a) – 0.81. b) – 0.31. c) 0.31. d) 1.96. ANSWER: a TYPE: MC DIFFICULTY: Moderate KEYWORDS: standardized normal distribution, value 6.
