Machine Machine Machine Machine 1 3 4 6.4 8.9 11.0 9.7 7.8 7.4 10.1 12.7 5.4 9.5 9.6 11.9 7.3 10.1 10.0 10.7 8.3 9.2 8.9 11.1 7.4 10.1 8.6 11.7 (a) At the a = 0.05 level of significance, what is the difference, if any, in the population mean times among the four machines? State the null and alternative hypotheses. O Ho: H1 $ 12 * M3 # H4 Ha: M 1 = 1 2 = M3 = 14 O Ho: M 1 = H2 = M3 = 14 Ha : H 1 # 12 * H 3 # 14 O Ho: At least two of the population means are equal. H2: At least two of the population means are different. O Ho: Not all the population means are equal. Ha: M 1 = M2 = M3 = H 4 O Ho: M 1 = H2 = M3 = 14 Ha: Not all the population means are equal.
