(a) Interpretation: The least square analysis needs to be performed to determine the intercept, slopeand regression statistics, including the standard deviation about regression. Concept introduction: The least square analysis is defined as the method in which the final answer for the set of data points is calculated by the minimizing the summation of residue of set of data point from the given curve. The equation for straight line is represented as follows: y = m x + c σ x = ( ∂ x ∂ m ) 2 ( σ m ) 2 + ( ∂ x ∂ c ) 2 ( σ c ) 2
