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?

Price 2300 1800 2500 2700 2000 1700 1500 2700

Quality Score 74 73 70 66 63 62 52 68
