Find the area under the normal curve. Draw the illustration.
Between z= –2.38 and z= 1.42
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.
