Question

NHL Assists and Total Points The number of assists and total number of points for a sample of NHL scoring leaders from the NHL are shown.

The correlation coefficient for the data is =r1 and =α0.01. Should regression analysis be done?

The regression analysis should or should not be done.

y' = a+bx

b= Find y' when x =85

y' =

Assists x	65	67	83	58	59	68	44
Total points y	75	77	93	68	69	78	54

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
