dstrbutad populaticn from a sarple?
O.99
1.65
1.96
2.58

Answer 1

Z score with a confidence level of 95% is 1.96

While determining the margin of error for the normally distributed population from the sample, the z score of the confidence level of 95% is 1.96

The same is to be considered

Therefore the third option is correct
