Anyone know how to get me started?
Calculate b0 and b1 and make an equation of regression line
for the set of data given in Table 3
Table 3
x y
1 12
2 15
3 16
5 18
6 21
8 23

If you need to show the work by hand, you can develop the regression equation in the following format:
predicted y = a + bx
...where a represents the yintercept and b the slope.
To get to that point, here are some formulas to calculate along the way.
To find a:
a = (Ey/n)  b(Ex/n)
Note: E means to add up or to find the total.
To find b:
b = SSxy/SSxx
To find SSxy:
SSxy = Exy  [(Ex)(Ey)]/n
To find SSxx:
SSxx = Ex^2  [(Ex)(Ex)]/n
I hope this will help get you started. 
Thank you!!!
