A study was carried out to investigate the relationship between the hardness of molded plastic (y, in Brinell units) and the amount of time elapsed since termination of the molding process (x, in hours). Summary quantities include n = 15, SSResid = 1236.046, and SSTo = 25460.897. Calculate the coefficient of determination. (Give the answer to four decimal places.)

Answer: The coefficient of determination is 0.04854.

Step-by-step explanation:

Since we have given that

n = 15

[tex]SS_{resid}=1236.046\\\\SS_{TO}=25460.897[/tex]

So, we need to find the Coefficient of determination:

So, we get :

Coefficient of determination is given by

[tex]R^2=\dfrac{SS_{Resid}}{SS_{TO}}\\\\R^2=\dfrac{1236.046}{25460.897}\\\\R^2=0.04854[/tex]

Hence, the coefficient of determination is 0.04854.
