Soltuion:
(a) Complete column C to find the product x×:
- In cell
C1, enter the formula:=A1*B1 - Drag the fill handle down to apply the formula to all rows in column C.
(b) Find the sum of the x column:
- Below the last entry in column A (say
A9), enter the formula:=SUM(A1:A8)
(c) Find the sum of the y column:
- Below the last entry in column B (say
B9), enter the formula:=SUM(B1:B8)
(d) Find the sum of the x× column:
- Below the last entry in column C (say
C9), enter the formula:=SUM(C1:C8)
(e) Find the sum of x2:
- Create a new column (e.g., column E). In
E1, enter the formula:=A1^2 - Drag the fill handle down to apply the formula to all rows in column E.
- Below the last entry in column E (say
E9), enter the formula:=SUM(E1:E8)
(f) Find the sum of y2:
- Create a new column (e.g., column F). In
F1, enter the formula:=B1^2 - Drag the fill handle down to apply the formula to all rows in column F.
- Below the last entry in column F (say
F9), enter the formula:=SUM(F1:F8)
