Question
Use a standard normal table to obtain the areas under the normal curve d below. Sketch a standard normal curve and shade the area of interest a. The area either to the left of 1.56 or to the right of 1.06. b. The area either to the left of 0.57 or to the right of 1.59. Cick here to view page 1 of the normal distribution table, OA ??. ??. 1.561.06 1.56 1.06 -1.561.06 The area either to the left of-1.56 or to the right of 1.06 is? Round to four decimal places as needed.) b. Which of the following graphs is correct? OA. ??. 0 0.57 1.59 0.57 1.59 The area either to the left of 0.57 or to the right of 1.59 is Click to select your answer(s).Explanation / Answer
a. We need to find
P(z < -1.56) + P(z > 1.06)
Using z tables,
0.0594 + 0.1446
= 0.2040.
The correct graph is A.
b. We need to find P(z < 0.57) + P(z > 1.59)
Using z tables
= 0.7157 + 0.0559
= 0.7716.
