Σx=28
Σy = 136
Σxy=596
Σx2= 140
136 = 7a + 28b
596 = 28a + 140b
∴b = 1.86
And substituting in one of the equations we acquire
a = 12
∴ Regression line = y = 12 + 1.86x
Or, Sales in ('000s of units) = 12.00 + 1.86 (no of years)
We utilize this expression for forecasting, for 8th year sales = 12 + 1.86 (8)
=26.88 that is 26,888 units.
