Confidence Interval vs. Confidence Level Confidence Interval Range: I’ll clean the dishes between Monday at 2pm and next September. Confidence interval is a range of values that is expected to include an... The equation for the confidence interval around a mean is given below. where z α /2 is the standard normal distribution z score with a tail area of α /2. We will use the normal distribution in this example.

how to find z score given confidence level and alpha

Find the critical value z subscript alpha divided by 2zα/2

Step 1: Subtract the confidence level (Given as 95 percent in the question) from 1 and then divide the result by two. This is your alpha level , which represents the area in one tail. (1 – .95) / 2 = .025...
