1. Find the area under the standard normal curve between z = -1.5 and z = 2.5.
2. Find the area under the standard normal curve to the right of z = -1.25.
3. Find the area under the standard normal curve to the left of z = 1.25.
4. Use the standard normal distribution to find P(-2.50 < z < 1.50)
5. For the standard normal curve, find the z-score that corresponds to the 90th percentile
6. For the standard normal curve, find the z-score that corresponds to the first quartile.
7. Find the z-scores for which 98% of the distribution's area lies between -z and z.
