A magazine tested LCD televisions. The table below shows the overall quality score and cost in hundreds of dollars. Use the rank correlation coefficient to test for a correlation between the two variables. Use a significance level of a = 0.01. Based on these results, can youexpect to get higher quality by purchasing a more expensive LCD television?QualityCost79 75747167666461615857 D27 3140 2319142723151419Spearman's Rank Correlation CoefficientClick the icon to view the critical values of Spearman's rank correlation coefficient.Determine the null and alternative hypotheses for this test.
