     According   to a high-profile realtor, houses in the sleepy town of Sun Beach have shown   higher appreciation over the past three years than have houses in the   bustling town of North Arden. To test the realtor's claim, an economist has   found fourteen recently sold homes in Sun Beach and fourteen recently sold   homes in North Arden that were owned for exactly three years. The following   table gives the appreciation (expressed as a percentage increase) for each of   the twenty-eight houses.      Appreciation rates in percent   Sun Beach   13.2;10.3;7.2;11.5;10.8;10.1;8.4;10.0;8.1;12.4;13.5;15.2;15.9;9.3   North Arden   11.1;10.5;9.7;7.6;12.0;4.3;9.7;5.3;8.4;8.2;10.4;8.4;6.1;6.7   Send data   to Excel      Assume that the two   populations of appreciation rates are normally distributed and that the   population variances are equal. Can we conclude, at the 0.05 level of   significance, that houses in Sun Beach have higher appreciation over the past   three years than houses in North Arden?      Perform a one-tailed test.   Then fill in the table below.      Carry your intermediate   computations to at least three decimal places and round your answers as   specified in the table. (If necessary, consult a list of formulas.)
