Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $10,000 and $40,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online le below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error. XE a. For a margin of error of :t $500 , the required sample size is n = b. For a margin of error of :l: $170 , the required sample size is n = NW c. For a margin of error of i $130 , the required sample size is n = d. Would you recommend trying to obtain the $130 margin of error? Explain.
