A magazine tested LCD televisions. The table below shows the overall quality score and cost in hundreds of dollars. Use the rank corelation coefficient to test for a correlation between the two variables. Use a significance level of a 0.01. Based on these results, can you expect to get higher quality by purchasing a more expensive LCD television?
