Rule of 68-95-99.7 is a rule of thumb for the probability of falling within 1, 2, and 3 standard deviations from the mean in the normal distribution. It can be used in a wide range of practical settings, especially when trying to make a quick estimate without a calculator or Z-table. While of the following is True? A. The area under a normal curve that is above Z = 2 (i.e. right tail area), is about 0.95 or 95%. B. The area under a normal curve that falls inside of |Z|=2, is about 0.95 or 95%. C. The area under a normal curve that is outside of |Z|=2, is about 0.95 or 95%. D. The area under a normal curve that is below Z = 2 (i.e. left tail area), is about 0.95 or 95%.

Transcribed Image Text:Rule of 68-95-99.7 is a rule of thumb for the probability of falling within 1, 2, and 3 standard deviations from the mean in the normal distribution. It can be used in a wide
range of practical settings, especially when trying to make a quick estimate without a calculator or Z-table. While of the following is True?
A. The area under a normal curve that is above Z = 2 (i.e. right tail area), is about 0.95 or 95%.
B. The area under a normal curve that falls inside of |Z|=2, is about 0.95 or 95%.
C. The area under a normal curve that is outside of |Z|=2, is about 0.95 or 95%.
D. The area under a normal curve that is below Z = 2 (i.e. left tail area), is about 0.95 or 95%.
