Suppose Z follows the standard normal distribution. Use the calculator provided, or this table, to determine the value of so that the following is true. P ( - c ≤ Z ≤ c )= 0.9586 Carry your intermediate computations to at least four decimal places. Round your answer to two decimal places.

Step 1
So, P(-c ≤ Z ≤ c) = 0.9586 means that the total probability in the tails is 1 - 0.9586 = 0.0414. Since the distribution is symmetric, each tail will contain half of this probability, or 0.0207. Show more…
