A study of Maths scores ( y ) with respect to x = Assessment scores yielded the following figures: n= 16 , xi=1,638.8, yi=303.34, xi2=179,841.6, xiyi= 32,310.95, yi2=6,434.08. If the equation of the least squares regression line isy=a+bx, then find and enter the value of b rounded to three decimal places in the space provided.
