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 meanamount 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 itemized deductions will show a sample mean within $200 of the population mean for each ofthe following sample sizes: 20, 50, 100, and 500? (Round your answers to four decimal places.)sample size n = 20sample size n = 50sample size n = 100sample size n = 500(b) What is the advantage of a larger sample size when attempting to estimate the population mean?OA larger sample lowers the population standard deviation.O A larger sample has a standard error that is closer to the population standard deviation.OA larger sample increases the probability that the sample mean will be within a specified distance of the population mean.OA larger sample increases the probability that the sample mean will be a specified distance away from the population mean.h

Answer The mean =16642The standard deviation =2400

State the conclusion based on the results of the test. According to the Federal Housing Finance Board, the mean price of a single-family home two years ago was $299,600. A real estate broker believes that because of the recent credit crunch, the mean price has decreased since then. The null hypothesis is not rejected. Choose the correct answer below. O A. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased from its level two years ago of $299,600. O B. There is sufficient evidence to conclude that the mean price of a single-family home has decreased from its level two years ago of $299,600. O C. There is sufficient evidence to conclude that the mean price of a single-family home has increased from its level two years ago of $299,600. O D. There is not sufficient evidence to conclude that the mean price of a single-family home has increased from its level two years ago of $299,600.
A tax assessor wants to estimate the mean property tax bill for all (1) homeowners living in Madison, Wisconsin. A survey completed three years ago indicated that the mean and standard deviation were $1200 and $1000. Assuming that the standard deviation is still about $1000, how large a sample of tax records should the tax assessor take in order to estimate the mean correct to within $100 with probability o.85?
Cynthia is president of an international chemical distribution company, Cchem. Weekly gross sales for Cchem has a mean of $1 million and standard deviation of $0.2 million; the distribution of sales is highly right-skewed. One week’s sales are independent of the sales in any other week. Use this information to answer questions 5 to 6 below. What is the probability that sales for the week of October 5, 2009 will be more than $1.25 million? In order for Cynthia to receive a bonus, Cchem’s annual sales must exceed $53 million. What is the probability that Cynthia will receive a bonus for the fiscal year starting in 2010? Assume there are 52 weeks in a year.
