Find the area under the normal curve in each of the following cases.

1. Between z = 0 and z = 1.63
2. Between z = 1.56 and = 2.51
3. Between z = -0.76 and z =1.35
4. Between z= -0.26 and z = -1.76
5. To the left of z = 2.35
6 To the right of z = -1.31
7. To the left of z = 0.35
8. To the left of z = 1.85
B. Find the indicated areas under the normal cueve, then convert it to percentage.
9. What percent of the area under the normal curve is between z=0.85 and x = 2.5?
10. What percent of the he area under the normal curve is between z = -2.10 and z = 2.10?
11. What percent of the area under the normal curve is between z = -1.10 and = -2.43?
