Most values of a standard normal distribution lie between:
A)0 and 1
B)−3 and 3
C)0 and 3
D)minus infinity and plus infinity

Question

Quizplus · Accepted Answer

The standard normal distribution has a mean of 0 and a standard deviation of 1. Therefore, approximately 68% of the values lie within one standard deviation of the mean. This means that values between -1 and 1 are within one standard deviation of the mean. Approximately 95% of the values lie within two standard deviations of the mean. This means that values between -2 and 2 are within two standard deviations of the mean. Finally, approximately 99.7% of the values lie within three standard deviations of the mean. This means that values between -3 and 3 are within three standard deviations of the mean. Therefore, most values of a standard normal distribution lie between -3 and 3.
