A sаmple cоntаins 76 оbservаtiоns, the sample standard deviation is in cell D5, and the confidence level is 90%. Write an Excel formula to compute the margin of error for a population mean confidence interval when the population standard deviation is unknown. Include all necessary Excel functions. Use cell references for inputs, as described above. Write as if you are using a single cell to compute the margin of error, including the formula/function for the critical value.
