Confidence level that can take any value from the drop down list 50 75 80 85 90 95 97 98 99 99 99 Each confidence level from the ones provided above has its In statistics a z score tells us how many standard deviations away a given value lies from the mean We use the following formula to calculate a z score z X where
Look up the Z score in standard normal distribution Z table that corresponds to a 90 confidence level As it is symmetric around zero you will find two values one positive Z 2 and one Hence the z value at the 90 percent confidence interval is 1 645 Let us consider the second case for which the given confidence level is 95 percent In this case we need to calculate the area
