You are estimating the cost ($K) of optical sensors based on the radius of the sensors. Using the preliminary calculations from a data set of 9 sensors, determine the equation of the line. (Round your intermediate calculations to 3 decimal places)

?Y = 2575

?X=21

?XY=9105

?X2=102

A) Cost = 149.780 + 58.428 (Radius)

B) Cost = 1.908 + 307.936 (Radius)

C) Cost = 190.520 + 50.040 (Radius)

  D) Cost = 50.040 + 190.520 (Radius)

Solution

Answer

In the equation of line, Y intercept is given by,

a = [
