2. The Ghana Revenue Authority (GRA) publishes annual figures on individual income tax returns in Statistics of Income, Individual Income Tax Returns. For the year 2009, the GRA reported that the mean tax of individual income tax returns was GHC 10,319. In actuality, the GRA reported the mean tax of a sample of 292,966 individual income tax returns from a total of more than 130 million such returns. a. Identify the population under consideration. b. Identify the variable under consideration. c. Is the mean tax reported by the GRA a sample mean or the population mean? d. Should we expect the mean tax x, of the 292,966 returns sampled by the GRA to be exactly the same as the mean tax, u, of all individual income tax returns for 2009? e. How can we answer questions about sampling error? For instance, is the sample mean tax T reported by the GRA likely to be within GHC 100 of the population mean tax, u?

Suppose the mean price for used cars is $10,198. A manager of a Kansas City used car dealership reviewed a sample of 50 recent used car sales at the dealership in an attempt to determine whether the population mean price for used cars at this particular dealership differed from the national mean. The prices for the sample of 50 cars are shown in the file named UsedCars. 12,400 10,400 12,100 10,000 11,000 8,895 7,675 9,975 6,350 10,470 9,895 11,250 8,795 12,500 9,340 10,150 9,200 9,395 11,000 10,640 10,000 7,500 8,000 10,440 10,200 10,300 9,740 9,280 10,930 8,000 9,000 7,680 9,400 10,730 7,350 12,240 11,970 8,240 9,910 10,080 9,440 8,970 9,500 10,050 10,130 11,400 8,500 7,500 9,090 10,500 (a) Formulate the hypotheses that can be used to determine whether a difference exists in the mean price for used cars at the dealership.

Official unemployment rates for the U.S. population are reportedon a monthly basis by the Bureau of Labor Statistics.For the period October, 2011, through January, 2012, theofficial unemployment rates were 8.9% (Oct.), 8.7% (Nov.),8.5% (Dec.), and 8.3% (Jan.).

According to the IRS, individuals filing federal income tax returns prior to March 31 received an average refund of $1,078 in 2018 . Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). b. For a sample 400 of individuals who filed a tax return between April 10 and 15 , the sample mean refund was $920. Based on prior experience a population standard deviation of a=1,800 may be assumed. What is the p -value (to 4 decimals)? c. Using , can you conclude that the population mean refund for "last minute" filers is less than the population mean refund for early filers? yes or no d. Repeat the preceding hypothesis test using the critical value approach. Using a=0.05 what is the critical value for the test statistic (to 3 decimals)? Enter negative value as negative number. State the rejection rule: Reject if is the critical value. choices: greater than or equal to, greater…
