Treatment 1 |
Treatment 2 |
Treatment 3 |

10 | 4 | 3 |

4 | 5 | 5 |

9 | 5 | 6 |

7 | 9 | 6 |

**a.** State the null hypothesis and the alternate
hypothesis.

*H*_{0}:
(Click to
select) The treatment means are not all the
same. The treatment means are the same.

*H*_{1}:
(Click to
select) The treatment means are the same. The
treatment means are not all the same.

**b.** What is the decision rule? **(Round
the final answer to 2 decimal places.)**

Reject *H*_{0} if the test statistic is greater
than
.

**c.** Compute SST, SSE, and SS total.
**(Round the final answers to 3 decimal places.)**
