We input simply the data to the calculator using the stat mode on the right x and y columns. The coefficient of lnear regression, r2 is equal to 0.67. The equation in the calculator resulted to y = 0.

We input simply the data to the calculator using the stat mode on the right x and y columns. The coefficient of lnear regression, r2 is equal to 0.67. The equation in the calculator resulted to y = 0.5 x + 3. The low r^2 means the relationship is not linear and the equation is not accurate to use.
