Quizplus · Accepted Answer

The probability $P(z < -0.31)$ using the standard normal distribution can be found using a Z-table or a calculator designed for statistics. The value corresponds to the area under the standard normal curve to the left of $z = -0.31$. This area is 0.3783, which means the probability that $z$ is less than -0.31 is 0.3783.
