Data from problem 52

A researcher chooses and interviews a group of 15 male workers in an automobile plant. The researcher then gives a score \((x)\) ranging from 1 to 20 based on a scale of patriotismthe higher the score, the more patriotic the person appears to be. Each person is then given a written test and is scored ( \(y\) ) on his patriotism. Is there a correlation between the researcher score and the test score, and, if so, is it significant at the \(5 \%\) or the \(1 \%\) significance level?
