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. Which is significantly equal to the expected general mean i.e. 87 (t-test 1 sample) No Subjek 1 2 3 4 5 6 7 8 9 10 A1 90 80 80 100 80 80 90 90 90 80 A2 90 90 70 80 80 70 70 70 60 60 A3 80 70 90 80 80 70 70 70 50 50 Being tested the effect of 3 kinds of medical glue formula on the time of wound closure with the following data: Formula a Formula b Formula c 13 13 4 10 11 1 8 14 3 11 14 4 Calculate in detail SSTR, SSE, SST (in 2 ways), MSTR and MSE.
