You are estimating the cost of optical sensors based on the RADIUS of the sensors. You decide to find out the coefficient of determination (R2) as part of determining the goodness of fit of an equation. Using the preliminary calculations below, find out the R2 and determine its meaning.

Given:
The Sum of(Yi - Ybar)squared = 147172
The Sum of(Yhat - Ybar)squared =11008
The Sum of (Y - Yhat)squared = 136164

Select the correct statement:
92.52% of the variation in the radius is being describeed by the cost.
7.48% of the variation in the cost is being describeed by the radius.
92.52% of the variation in the cost is being describeed by the radius.
7.48% of the variation in the radius is being describeed by the cost.
