Question

Quizplus · Accepted Answer

The probability that a standard normal variable z lies between 0 and 3.01 is the area under the standard normal curve from 0 to 3.01. This is approximately 0.4987, as the total area from 0 to infinity is 0.5 and the area from 0 to 3.01 is very close to this value.
