A) symmetric about $\mu$
B) mound-shaped (or bell shaped)
C) $P ( \mu - 3 \sigma

Question

Which of the following statements is not a property of the normal curve? 
A) symmetric about $\mu$
B) mound-shaped (or bell shaped)
C) $P ( \mu - 3 \sigma < x < \mu + 3 \sigma ) \approx .997$
D) $P ( \mu - \sigma < x < \mu + \sigma ) \approx .95$

The correct property related to the normal curve for $P ( \mu - \sigma < x < \mu + \sigma )$ is approximately 0.683, not 0.95. The statement in D incorrectly describes the proportion of data within one standard deviation of the mean for a normal distribution.
