Final answer:
To find the area under the standard normal curve to the right of a given z-value, look up the area to the left of the z-value in a z-table and subtract it from 1.
Step-by-step explanation:
To find the area under the standard normal curve to the right of a given z-value, we can use a z-table. (a) For z=0.56, we look up the area to the left of 0.56 in the z-table and subtract it from 1. This gives us an area of 0.2861. (b) For z=-2.25, we look up the area to the left of -2.25 in the z-table and subtract it from 1. This gives us an area of 0.9878. (c) For z=2.07, we look up the area to the left of 2.07 in the z-table and subtract it from 1. This gives us an area of 0.0192. (d) For z=1.02, we look up the area to the left of 1.02 in the z-table and subtract it from 1. This gives us an area of 0.1522.
