This is in reference to Q 11 of May 2009 paper of IAI
We're given 3 treatments and 5 values each
We're asked to combine treatments 1 & 3, and then examine whether there is evidence to suggest that the average effect of treatments 1&3 is inferior to that of treatment 2.
Here, what would be the degrees of freedom using test statistic with distribution t_n1+n2-2 ?
Would it be 5+5-2 = 8 or 10+5-2 = 13 ?
What would be the 'n1' in the test statistic, 10 or 8?
Thanks a ton
