Identify the formula for the margin of error for the estimate of a population mean when the population standard deviation is unknown.


Expert Answer

Step 1

Margin of error:

Margin of error is a range of values that lie above and below the sample statistic of the confidence interval; it gives the percentage of number of points that differ in the obtained results from the population value.

Step 2

Margin of error is calculated as the product of critical value and standard deviation or the product of critica...
