3. You will need to use the critical values of the correlation coefficient, r, table found in section 14.4 of the e-text to answer these problems. a) Is a correlation coefficient of r = 0.867 when n = 16 significant at the 5% level? Why or why not? b) Is a correlation coefficient of r=-0.209 when n = 100 significant at the 1% level? Why or why not?
