Consider these 4 samples potentially drawn from 4 differentpopulations. Sample #1) 25 19 14 21 18 18 19 19 Sample #2) 25 15 2220 15 20 16 20 20 16 20 11 Sample #3) 22 16 23 13 14 19 18 10 11Sample #4) 12 11 13 10 25 19 Test the hypothesis using thesamples.
assuming that a = 0.05
Ho: u2 = u3
Ha: u2 not equal to u3
Ho: sigma 2 < = to sigma 3
Ha: sigma 2 > sigma 3
