The Normal Curve

Find the area under the normal curve in each of the following cases. 1. Between z = 0 and z = 1.63 2. Between z = 0 and z = -1.78 3. Between z = 1.56 and z = 2.51 4. Between z = -1.36 and z = 2.55 5. Between z = -2.46 and z = 1.55 6. Between z = -2.76 and z = -1.25 7. Between z = 1.26 and z = 1.78 8. Between z = -1.78 and z =-0.26 9. To the right of z = 2.35 10. To the right of z = -1.31 11. To the left of z = 0.35 12. To the left of z = -1.85 13. To the right of z =-0.95 14. To the right of a z =-0.75 15. To the right of z = -1.54Find the indicated area under the normal curve, then convert it to percentage. 1. What percent of the area under the normal curve is between z = 0.85 and z = 2.5? 2. What percent of the area under the normal curve is between z = -1:00 and z = 1.00? 3. What percent of the area under the normal curve is between z = -2.10 and z = 2.10? 4. What percent of the area under the normal curve is between z = -2.43 and z = -1.10? 5. What percent of the area under the normal curve is between z = 1.03 and z = 2.83?1.
