Question

1. Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to four decimal places.)

The area between z = 0 and z = 3.00 is ______.

2. Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to four decimal places.)

The area between z = 0.41 and z = 1.82 is ______.

3. Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.)

P(−2.12 ≤ z ≤ −0.35) = ______.

4. Recall that the Standard Normal Distribution Table gives us areas to the left of z. Here we wish to find

P(z ≥ 0.24), which corresponds to the area to the right of z = 0.24.Therefore, we will use the following formula.

P(z ≥ 0.24) = ________ − P(z ≤ 0.24)
