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 = 0.05. Based on these results, can you expect to get higher quality by purchasing a more expensive LCD television? Quality 78 74 71 69 65 Cost 27 28 37 23 20 Determine the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: Ps #0 H₁: Ps = 0 O C.
