What is the planning value for the population standard deviation? 4450 (a) How large a sample should be taken if the desired margin of error is $500? 196 (b) How large a sample should be taken if the desired margin of error is $2007 344 (c) How large a sample should be taken if the desired margin of error is $100? 344 (d) Would you recommend trying to obtain the $100 margin of error? Explain. Sampling college graduates to obtain the $100 margin of error would be viewed as too expensive and too much effort by most researchers.
