You are estimating the cost of optical sensors based on the POWER OUTPUT of the sensor. You decide to calculate the coefficient of determination (R^2) as part of determining the goodness of fit of an equation. Using the preliminary calculations below, calculate the R^2 and determine its meaning. Σ(Yι - Ῡ)² =147172 Σ(Ŷ - Ῡ)² = 132369 Σ(Y - Ŷ)² =14804
a) 89.94% of the variation in the power is being explained by the cost.
b) 10.06% of the variation in the cost is being explained by the power.
c) 10.06% of the variation in the power is being explained by the cost.
d) 89.94% of the variation in the cost is being explained by the power.© BrainMass Inc. brainmass.com October 2, 2020, 5:31 am ad1c9bdddf
