Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online file below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error. Open spreadsheet a. For a margin of error of +$300, the required sample size is n = b. For a margin of error of $210, the required sample size is n = C. For a margin of error of +$140, the required sample size is n = d. Would you recommend trying to obtain the $140 margin of error? Explain. Check My Work Reset
