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.)
Ages of Best Actresses and Actors Listed below are ages of actresses and actors at the times that they won Oscars. Corresponding ages are matched so that they are from the same year. Is there sufficient evidence to conclude that there is a linear correlation between ages of best actresses and best actors?
