# What is the area under the standard normal curve between z = —1 .6 and  z = 1 .9 ?

To determine

To calculate: The area between z=1.6 and z=1.9 under the standard normal curve.

Explanation

Given Information:

The standard normal curve is between z=1.6 and z=1.9.

Refer to the Appendix C of the book.

Formula Used:

The area under the curve is,

Pr(azb)=Pr(az0)+Pr(0zb)

Calculation:

Consider the standard normal curve between z=1.6 and z=1.9.

Thus the area under the curve will be,

Pr(1.6z1.9)=Pr(1.6z0)+Pr(0z1.9)

Appendix C gives the area under the standard normal curve between z=0 and z=z0 for z0
