what does an asterik mean in a confidence interval mean for statistics

Expert Solution

In confidence interval:

Z^* means critical points for the Z distribution.

For example, in a two-tailed test, Z^*, critical values of Z for 95% is 1.96.

This means : If the observed Z score is greater than 1.96 or less than - 1.96, Reject H0.
