Testing for a Linear Correlation. In Exercises 13–28, construct a scatterplot, and find the value of the linear correlation coefficient r. Also find the P-value or the critical values of r from Table A-6. Use a significance level of a = 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 10-2 exercises.)

Transcribed Image Text:27. Sports Diameters (cm), circumferences (cm), and volumes (cm³) from balls used in different
sports are listed in the table below. Is there sufficient evidence to conclude that there is a linear cor-
relation between diameters and circumferences? Does the scatterplot confirm a linear association?
