Describe Scatter plot and correlation

Costs of Televisions Listed below are prices (in dollars) as well as 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, the 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
