Take another look at the data from the sample below (a = 5% = 0.05): a. Calculate in detail SSTR, SSE, SST (in 2 ways), MSTR and MSE. Also prove that there are differences in the 3 sample groups. b. Which sample groups are different? (compare A1 and A2, A1 and A3 and A2 and A3) with a two sample t test. c.
