| Regression analysis is being used to find the line of best fit (y = a + bx) from five pairs of data. The calculations haveproduced 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)?
 A   146
 B   152
 C   210
 D   245
