a) If r2 = 0.95, n=11 and the ( )2 = 100,what is 2 2 ?

b) If r2 = 1, then 2 in (45a) can be shown to have what type of relationship with SST

and SSR?

c) What relationship exists between and Y where r2 = 1?

d) What relationship exists between and Y where r2 = 0?

e) Given the following information: r2 = 0.95, n = 10 and k = 2 what is the t-value for b1?

f) In (e), you calculated t-value at the 0.05 level of significance; what statistical decision can you make about b1?
