5. Determine the total area under the standard normal curve in parts (a) through (c) below. (a) Find the area under the normal curve to the left of z= -1 plus the area under the normal curve to the right of z = 1. The combined area is (Round to four decimal places as needed.) (b) Find the area under the normal curve to the left of z= -1.56 plus the area under the normal curve to the right of z= 2.56. The combined area is (Round to four decimal places as needed.) (c) Find the area under the normal curve to the left of z= -0.26 plus the area under the normal curve to the right of z=1.40. The combined area is (Round to four decimal places as needed.) 6. Find the z-score such that the area under the standard normal curve to the left is 0.48. is the z-score such that the area under the curve to the left is 0.48. (Round to two decimal places as needed.) 7. Find the z-score such that the area under the standard normal curve to the right is 0.11. The approximate z-score that corresponds to a right tail area of 0.11 is (Round to two decimal places as needed.) 8. Find the z-scores that separate the middle 66% of the distribution from the area in the tails of the standard normal distributic The z-scores are (Use a comma to separate answers as needed. Round to two decimal places as needed.)
