Consider these 4 samples potentially drawn from 4 different populations. Sample #1) 25 19 14 21 18 18 19 19 Sample #2) 25 15 22 20 15 20 16 20 20 16 20 11 Sample #3) 22 16 23 13 14 19 18 10 11 Sample #4) 12 11 13 10 25 19 Test the hypothesis using the samples above.
Assuming that a = 0.05
Ho: u1 = u2
Ha: u1 not equal to u2
Ho: u2 < = u3
Ha: u2 > u3
