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 $32,000 and $50,600. A 95% confidence interval estimate of the population me annual starting salary is desired. (Round your answers up to the nearest whole number.) What is the planning value for the population standard deviation? 4650 (a) How large a sample should be taken if the desired margin of error is $500? 332 X (b) How large a sample should be taken if the desired margin of error is $300? 2077 X (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? O No, sampling the number of college graduates required to obtain the $100 margin of error would be viewed as too expensive and too much effort by most researchers. O Yes, sampling the number of college graduates required to obtain the $100 margin of error would be viewed as easy to obtain by most researchers
