Transcribed Image Text:Find the critical value z/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 as the equivalent percentage value.
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 standard normal distribution.
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 = Z0.15/2

Z0.15/2 = Z0.075
Z0.075 = O
