Answer: To determine a functional relationship between the attenuation coefficient and
Chapter 8, Problem 12(choose chapter or problem)
To determine a functional relationship between the attenuation coefficient and the thickness of a sample of taconite, V. P. Singh [Si] fits a collection of data by using a linear least squares polynomial. The following collection of data is taken from a graph in that paper. Find the linear least squares polynomial fitting these data. Thickness (cm) Attenuation coefficient (dB/cm) 0.040 26.5 0.041 28.1 0.055 25.2 0.056 26.0 0.062 24.0 0.071 25.0 0.071 26.4 0.078 27.2 0.082 25.6 0.090 25.0 0.092 26.8 0.100 24.8 0.105 27.0 0.120 25.0 0.123 27.3 0.130 26.9 0.140 26.2
