Chapter 10.2, Problem 30BSC

Large Data Sets. In Exercises 29-32, use the data from Appendix B to construct a scatter plot, find the value of the linear correlation coefficient r, and find either the P-value or the critical values of r from Table A-6 using α = 0.05. Determine whether there is sufficient evidence to support the 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.)

30. Flight Delays Refer to Data Set 15 in Appendix B and use the departure delay times and the arrival delay times.
