The general form of the regression model is
.
Using the sinusoidal regression calculator, we get that,
a = 33.690
b = 0.887
c = 1.337
d = 81.684
That is, the sine regression model is
.
Thus, option A is the sine regression model for the given data.
It's a to the power of 2
B to the power of 2
C to the power of 2
