Question:
#4 - Suppose the standard deviation of the population is = 107.9. If you want to be 97% confident of estimating the population mean to within a margin of error of E = 22.5, what sample size is required? Enter the number you get from the calculation to 3 decimal places. Do not round up, although normally you would need to do that to ensure the confidence being sought.
