Find the critical value za/2 that corresponds to the given confidence level. 85% The confidence level is the probability or area 1-a, where a is the complement of the confidence level. It is often expressed Since the given confidence level is 85%, the value of a is 1-0.85. Compute a. 1-0.85 = 0.15 (Type an integer or a decimal.) The critical value z/2 is the positive z value that is at the boundary separating an area of a /2 in the right tail of the standa Use a standard normal table to find the critical value, z/2. The area to the left of za/2 is 0.925. Za/2 = 20.15/2 Zo.15/2 = Z0.075 Z0.075 = (Round to two decimal places as needed.)
