Testing for a Linear Correlation. In Exercises 13-28, construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r from Table A-5 using a0.05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables.
