Find the area of the shaded region under the standard normal distribution.

For the standard normal probability distribution, the area to the left of the $\mathrm{mean}$ is:

Find the area under the standard normal distribution to the left of a z-score of $1.21$.

Find the area under the standard normal distribution to the right of a z-score of $-0.44$.

Find the z-score such that $P$(Z < z)$=0.6331$.

Find the z-score corresponding to the probability/area shown under the standard normal curve below.

Normal Distribution If the following data are randomly selected, which are expected to have a normal distribution?

a. Weights of Reese’s Peanut Butter Cups

Standard Normal Distribution. In Exercises 17–36, assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. In each case, draw a graph, then find the probability of the given bone density test scores. If using technology instead of Table A-2, round answers to four decimal places.
