You may need to use the appropriate appendix table or technology to answer this question. The Wall Street Journal reports that 33% of taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deductions on their federal income tax return. The mean amount of deductions for this population of taxpayers was $16,642. Assume the standard deviation is a $2,400, (a) What is the probability that a sample of taxpayers from this income group who have Remized deductions wit show a sample mean within $200 of the population mean for each of the following sample sizes: 30, 50, 150, and 3007 (Round your answers to four decimal places) sample size - 30 sample size - 50 sample size - 150 sample size n-300 (b) What is the advantage of a larger sample size when attempting to estimate the population mean? OA larger sample increases the probability that the sample mean will be a specified distance away from the population mean, A larger sample increases the probability that the sample mean will be within a specified distance of the population mean. A larger sample lowers the population standard deviation. A larger sample has a standard error that is closer to the population standard deviation.
