Answer 2

The value of z-score with a confidence level of 95% in finding margin of error for the mean of a normally distributed population from a sample is 1.96.

What is normally distributed data?

Normally distributed data is the distribution of probability which is symmetric about the mean.

• The mean of the data is the average value of the given data.
• The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

The confidence level is 95% when finding the margin of error for the mean of a normally distributed population from a sample.

The critical z score value for the confidence level of 95% is 1.96 and +1.96 standard deviation.

Thus, the value of z-score with a confidence level of 95% in finding margin of error for the mean of a normally distributed population from a sample is 1.96.
