Scatter plot and correlation.

Costs of Televisions Listed below are prices (in dollars) and quality rating scores of rare-projection televisions (based on data from Consumer Reports). All of the televisions have screen sizes of 55 in or 56 in. Is there sufficient evidence to conclude that there is a linear correlation between the price and the quality rating score of rare-projection televisions? Does it appear that as the price increase, quality score also increases? Do the results suggest that as you pay more, you get better quality?
