Year January Inflow February Inflow
1976 2.89 2.45
1977 3.57 2.57
1978 4.18 3.17
1979 4.71 3.93
1980 4.12 2.93
Using Feb. Inflow as the dependent variable and Jan. Inflow as the independent variable.
------------
Feb Inflow is the "y" variable; Jan Inflow is the "x" variable.
Use the "LinReg" function of a TI calculator to get the following:
---------------------
What is the equation of the regression line?
y = 0.7758458x - 0.01114368
---------------------------------
What is the value of the coeifficent of determination?
Ans: R^2 = 0.830495...
---------------.
What is the value of the linear correlation coeefficent?
Ans: R = 0.91131525..
