You are estimating the cost ($K) of optical sensors based on the power output of the sensor. Using the preliminary calculations from a data set of 8 sensors, determine the equation of the line. (Round your intermediate calculations to 3 decimal places)
ΣY = 2575 ΣX=680 ΣXY=241400 ΣX2=62600
A) Cost = 6.763 + 3.786 (Power)
B) Cost = 4.693 + (-77.005) (Power)
C) Cost = 3.786 + 6.763 (Power)
D) Cost = -77.005 + 4.693 (Power)© BrainMass Inc. brainmass.com October 17, 2018, 12:43 pm ad1c9bdddf
y = m x + b
<y> = sum(y)/n = 2575/8 = 321.875
<x> = sum(x)/n = 680/8 = 85
As per given data, line of best fit is estimated in clear calculations for a cost vs power chart.
