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 α=0.01. Based on these​ results, can you expect to get higher quality by purchasing a more expensive LCD​ television?   Quality     75 74
