Assignment:
Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r from Table A-6 using ?? =0 .05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-3 exercises.)
