Historical data show that during the recession of 1990-1991, the natural rate of unemployment was about 5.9 percent while the actual rate of unemployment was 7.0 percent. A decade later, during the 2001 recession, the natural rate of unemployment had fallen to 4.8 percent while actual unemployment was 6.0 percent. Which of the following statements is correct regarding these two short recessions? The actual unemployment rate was higher during the recession of 1990-1991, but cyclical unemployment was higher in 2001. Both the actual unemployment rate and cyclical unemployment were higher in 2001. The actual unemployment rate was higher in 2001, but cyclical unemployment was higher from 1990-1991. Both the actual unemployment rate and cyclical unemployment were higher during the recession of 1990-1991.

The following is a sample of unemployment rates (in percentage points) in the US sampled from the period 1990-2004: 4.2, 4.7, 5.4, 5.8, 4.9. (a) Compute the sample mean, x, and standard deviation, s, using the formula method. (Round your answers to one decimal place). (b) In what range does the empirical rule predict that approximately 95% of the unemployment rates will fall? (c) Determine the actual percentage of unemployment rate that falls in the range predicted in part (b). (d) Which gives the more accurate prediction of the percentage in part (c), Chebyshev’s rule or the Empirical rule? [Give reason(s)].

The following is a sample of unemployment rates (in percentage points) in the US sampled from the period 1990 - 2004; 4.2, 4.7, 5.4, 5.8, 4.9. a) Compute the sample mean, x̄, and the sample standard deviation, s, using the formulas defining these quantities, not the STAT menu in your calculator. Round your answers to one decimal place. (You can check your answers with STAT menu in calculator!) b) In what range does the empirical rule predict that approximately 95% of the unemployment rates will fall? c) Determine the actual percentage of unemployment rates that fall in the range predicted in part b).
