The following data was reported on total Fe for four types of iron formation (1 = carbonate, 2 = silicate, 3 = magnetite, 4 = hematite).

1: 20.6 28.1 27.8 27.0 27.9 25.2 25.3 27.1 20.5 31.2
2: 26.5 24.0 26.2 20.2 23.6 34.0 17.1 26.8 23.7 24.8
3: 30.2 34.0 27.5 29.4 28.3 26.2 29.9 29.5 30.0 35.8
4: 36.6 44.2 34.1 30.3 32.0 33.1 34.1 32.9 36.3 25.2
 

Carry out an analysis of variance F test at significance level 0.01. State the appropriate hypotheses.

H0: ?1 ≠ ?2 ≠ ?3 ≠ ?4
Ha: at least two ?i's are equalH0: ?1 = ?2 = ?3 = ?4
Ha: all four ?i's are unequal    H0: ?1 ≠ ?2 ≠ ?3 ≠ ?4
Ha: all four ?i's are equalH0: ?1 = ?2 = ?3 = ?4
Ha: at least two ?i's are unequal
