(a) At the a = 0.05 level of significance, can we reject the null hypothesis that the means of the three treatments are equal?
State the null and alternative hypotheses.
O Ho: HA + Hg + HC
H: HA = HB = HC
O Ho: HA = Hg = HC
H: HA * HB * HC
O Ho: At least two of the population means are equal.
H: At least two of the population means are different.
O Ho: HA = HB = "C
%3D
H: Not all the population means are e
O Ho: Not all the population means are equal.
H: HA = HB = HC
