To find the area under the standard normal curve between $z = -1.9$ and $z = 2.2$, we look up the values in the standard normal distribution table or use a calculator. The table gives us the area to the left of $z = -1.9$ and $z = 2.2$. The area to the left of $z = 2.2$ is approximately 0.9861, and the area to the left of $z = -1.9$ is approximately 0.0287. Subtracting these two gives us the area between them: $0.9861 - 0.0287 = 0.9574$.

Find the area under the standard normal curve that lies between z=−1.9 and z=2.2. \text { Find the area under the standard normal curve that lies between } z = - 1.9 \text { and } z = 2.2 \text {. } Find the area under the standard normal curve that lies between z=−1.9 and z=2.2.
