Question

You may need to use the appropriate appendix table or technology to answer this question. Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $41,000 and $59,600. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. (Round your answers up to the nearest whole number.) What is the planning value for the population standard deviation? (a) How large a sample should be taken if the desired margin of error is $500? (b) How large a sample should be taken if the desired margin of error is $300? (c) How large a sample should be taken if the desired margin of error is $100? (d) Would you recommend trying to obtain the $100 margin of error? Explain.

The Economic Policy Institute periodically issues reports on
wages of entry level workers. The institute reported that entry
level wages for male college graduates were $21.68 per hour and for
female college graduates were $18.80 per hour in 2011.† Assume the
standard deviation for male graduates is $2.30, and for female
graduates it is $2.05. (Round your answers to four decimal
places.)
