Question

Find the area under the standard normal curve to the left of z = 0.49 and to the right of z = 2.05. Round your answer to four decimal places, if necessary.

Answer 1

Answer:

Step-by-step explanation:

We would determine the area to the left of z = 0.49 on the normal curve and subtract it from the area to the left of z = 2.05 on the normal curve

Therefore,

For z = 0.49,

Probability value = 0.6879

For z = 2.05

Probability value = 0.9798

Therefore, the area under the standard normal curve to the left of z = 0.49 and to the right of z = 2.05 is

0.9798 - 0.6879 = 0.2919

Answer 2

The area will be "0.7081".

According to the question,

The area under standard normal curve to left of,

• $z = 0.49$

To the right of,

• $z = 2.05$

Now,

The Area will be:

= $P[z< 0.49]+P[z>2.05]$

= $P[z< 0.49]+1-P[z< 2.05]$

= $0.6879+1-0.9798$

= $0.7081$

Thus the above answer is right.
