In the formula CL% confidence interval = x ZcL*
what is Z95% ?

In the formula for confidence interval; CI = X ± Z(s/√n)

what is Z95% ?

>> Z95% means critical z value for 95% Confidence level.

>> Z95% = 1.96

Step-by-step explanation:

The formula for confidence interval is given as;

CI = x¯ ± Z(s/√n)

Where:

x¯ is the mean

Z is the critical value for a particular %CL

s is standard deviation

n is sample size

Thus, Z95% means critical z value for 95% Confidence level.

From tables, the z-value for a confidence level of 95% is 1.96
