Government survey takers determine that typical family expenditures each month in the year designated as the base year are as follows: 20 pizzas, $10 eachrent of apartment, $600 per monthgasoline and car maintenance, $100 per monthphone service (basic service plus 10 long-distance calls), $50 per monthin the year following the base year, the survey takers determine that pizzas have risen to $11 each, apartment rent is $640, gasoline and maintenance have risen to $120, and phone service has dropped in price to $40.instructions: enter your responses by rounding the cpi to three decimal places and the rate of inflation to one decimal place.(a). find the cpi in the subsequent year and the rate of inflation between the base year and the subsequent year.(b). the family's nominal income rose by 5 percent between the base year and the subsequent year. are they worse off or better off in terms of what their income is able to buy?

Acompany is developing a new high­performance wax for cross country ski racing. in order to justify the price marketingwants, the wax needs to be very fast. specifically, the mean time to finish their standard test course should be less thanseconds for a former olympic champion. to test it, the champion will ski the course 8 times. the champion's times(selected at random) are 59.9 61.9 48.8 52.2 46.6 45.3 50.6 and 41.1 seconds to complete the test course. complete parts a and b below.a) should they market the wax? assume the assumptions and conditions for appropriate hypothesis testing are metfor the sample.assume=0.05. what are the null and alternative hypotheses? choose the correct answer below.b) suppose they decide not to market the wax after the test, but it turns out that the wax really does lower the champion'saverage time to less thanseconds. what kind of error have they made? explain the impact to the company of such anerror.

Assume that the following conditions exist: a. all banks are fully loaned up- there are no excess reserves, and desired excess reserves are always zero. b. the money multiplier is 5 .     c. the planned investment schedule is such that at a 4 percent rate of interest, investment =$1450 billion. at 5 percent, investment is $1420 billion. d. the investment multiplier is 3 . e.. the initial equilibrium level of real gdp is $12 trillion. f. the equilibrium rate of interest is 4 percent now the fed engages in contractionary monetary policy. it sells $1 billion worth of bonds, which reduces the money supply, which in turn raises the market rate of interest by 1 percentage point. calculate the decrease in money supply after fed's sale of bonds: $nothing billion.
