NHL Assists and Total Points A random sample of scoring leaders from the National Hockey League (NHL) showed the following numbers of assists and total points. Based on these data, can it be concluded that there is a significant relationship between the two? Draw the scatter plot for the variables. NHL Assist and Points Compute the value of the correlation coefficient. Round your answer to at least three decimal places. r= Assists 59 68 44 58 67 69 Total points 109 101 95 109 91 89 State the Hypothesis. H0: H1: Test the significance of the correlation coefficient at =α0.05, using The Critical Values for the PPMC Table. Critical value(s): +or- = Reject or do not reject the null hypothesis.
