explain the following questions

You may need to use the appropriate appendix table or technology to answer this question. Suppose In 2018, RAND Corporation researchers found that 77% of all individuals ages 66 to 65 are adequately prepared financially for retirement, Many financial planners have expressed concern that a smaller percentage of those in this age group who did not complete high school are adequately prepared financially for retirement. (a) Develop appropriate hypotheses such that rejection of N, will support the conclusion that the proportion of those who are adequately prepared financially for retirement is smaller for people in the 66-69 age group who did not complete high school than it is for the population of the 66-69 year old. (Enter In for a as needed.} (b) In a random sample of 300 people from the 65-69 age group who did not complete high school, 159 were not prepared financially for retirement. What is the p- value for your hypothesis test? Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = (c] At a = 0.01, what is your conclusion? Do not reject He. We conclude that the percentage of 66- to 69-year-old individuals who are adequately prepared financially for retirement is smaller for those who did not complete high school. Reject Ho. We conclude that the percentage of 66- to 69-year-old individuals who are adequately prepared financially for retirement is smaller for those who did not complete high school. Reject Ho. We cannot conclude that the percentage of 66- to 69-year-old individuals who are adequately prepared financially for retirement is smaller for those who did not complete high school. Do not reject H,. We cannot conclude that the percentage of 66- to 69-vear-old individuals who are adequately pranarad financially far vatican(3) You and a classmate are assigned a project on which you will receive one combined grade. You each want to receive a good grade, but you also want to avoid hard work. In particular, here is the situation: If you both work hard, you get an A, which gives you each 40 units of happiness .If only one of you works hard, you both get a B, which gives you each 30 units of happiness. .If neither of you works hard, you both get a D, which gives each of you 10 units of happiness. . Working hard costs 25 units of happiness. (a) Fill in the following payoff matrix: Your decision Work Shirk Classmate's Work decision Shirk (b) What is the likely outcome? Explain your answer. T (c) If you get this classmate as your partner on a series of projects throughout the year, rather than only once, how might that change the outcome you predicted in part (b)?QUESTION 48 Consider three items that might be included in GDP: (1) the estimated rental value of owner-occupied housing and (2) the purchase of newly constructed houses and (3) the rental of an apartment. How are these three items accounted for when GDP is calculated? All three items are included in the consumption component of GDP. Item (1) and item (3) are included in the consumption component of GDP, while item (2) is included in the investment component of GDP. G Items (1) and (2) are included in the investment component of GDP, while item (3) is included in the consumption component of GDP. Item (2) Is included in the investment component of GDP and item (3) is included in the consumption component of GOP, Item (1) is not included in GOP at all because it is considered a used good. QUESTION 49 How is the real rate of interest determined? The real interest rate is set by the central bank of a nation, such as our Federal Reserve. The real interest rate is determined by the equilibrium of the supply and demand for loanable funds. The real interest rate is determined by the nominal interest rate plus the inflation rate. The real interest rate is determined by the demand for private savings and the supply of public savings. QUESTION 50 Which of the following occurs when the Ford Motor Company removes a 2020 Ford Taurus from inventory and sells it to an American household for $22.000? U.5. consumption increases by $22,000, U.5. investment decreases by $22,000, and U.S. GDP does not change. U.5. consumption increases by $22,000, U.S. investment does not change, and U.S. GDP Increases by $22.000. U.S. consumption does not change, U.S. investment decreases by $22,000, and U.S. GDP decreases by $22,000. U.5. consumption increases by $22.000, U.5. investment increases by $22,000, and U.S. GDP increases by $44,000
