An article discusses the calibration of a radiometer. Several measurements were made on the electromotive force readings of the radiometer (in volts) and the radiation flux (in kilowatts per square meter). The results (read from a graph) are presented in the following table. Part 1 out of 3 a. Compute the least-squares line for predicting heat flux from the signal output. Round to six decimal places, if necessary. y = + x

Solution

y = 19.892414 + 12.972843*X
