The mean amount of deductions for this population of taxpayers was $16,5642. Assume that the standard deviation is o = $2,460. If required, round your answer to two decimal places. (a) What are the sampling errors of x for itemized deductions for this population of taxpayers for each of the following sample sizas: 30, 50, 100, and 4007 E(x) =% 16,642 @ n o 30 $ Q 50 $ Q 100 $ D 400 $ Q (b) What is the advantage of a larger sample size when attempting to estimate the population mean? A larger sample| reduces v | @ the standard error and results in a(n)| more v | \\20 precise estimate of the population mean
