For a confidence level of 96% with a sample size of 55, find the z score for the right bound of the confidence interval. This requires taking NORMINV of the appropriate value. Show your answer to 3 decimals.
Homework Answers
Solution:
We are given
Confidence level = 96%
α = 1 - 0.96 = 0.04
α/2 = 0.04/2 = 0.02
For right side or upper 0.02 area, the critical Z value is given as below:
Z = 2.053749
Answer: Z = 2.054
