How do you find the area under a normal curve

Asked by admin @ in Mathematics viewed by 288 People

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.

Answered by admin @


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
