    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    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)

    y = m x + b

    <y> = sum(y)/n = 2575/8 = 321.875
    <x> = sum(x)/n = 680/8 = 85
