alphaαequals=0.010.01.

Weight, x	59205920	53205320	65006500	51005100	58405840	48004800
Variability in braking distance, y	1.761.76	1.921.92	1.911.91	1.591.59	1.691.69	1.501.50

find the critical value

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.
