C) can have a mean of 0 and a standard deviation of 1.
D) can have no values.

Question

Quizplus · Accepted Answer

The range of values for a normally distributed random variable can be from negative infinity to positive infinity, but values beyond 3 standard deviations from the mean are rare. Therefore, the range can be approximated as between -3σ and +3σ, where σ is the standard deviation.
