Regression analysis is being used to find the line of best fit (y = a + bx) from five pairs of data. The calculations have produced the following information: Σx = 129 Σy = 890 Σxy = 23,091 Σx2 = 3,433 Σy2 = 29,929 What is the value of ‘a’ in the equation for the line of best fit (to the nearest whole number)?
