Question

Find the area under the normal curve. Draw the illustration.

Between z= –2.38 and z= 1.42

Answer 1

To find the area under the normal curve between z-scores -2.38 and 1.42, we have to find the area left of 1.42 using z-table, and then subtract the area left of -2.38.

So we have:

$A=0.9222-0.0087=0.9135.$

Answer: 0.9135.
