Question

An experiment was conducted to see the effectiveness of two
antidotes to three different doses of a toxin. The antidote was
given to a different sample of participants five minutes after the
toxin. Twenty-five minutes later the response was measured as the
concentration in the blood. What can the researchers conclude with
α = 0.01?

Dose |

Antidote |
5 | 10 | 15 |

1 | 0.6 1.1 1.1 |
2.1 1.5 6.2 |
3.1 4.1 5.9 |

2 | 1.1 1.2 1.1 |
1.7 1.3 1.5 |
2.1 3.1 2.1 |

Compute the appropriate test statistic(s) to make a decision
about *H*_{0}.

**Antidote**: critical value = ; test
statistic =

Decision: ---Select--- Reject H0 Fail to reject H0

**Dose**: critical value = ; test
statistic =

Decision: ---Select--- Reject H0 Fail to reject H0

**Interaction**: critical value = ;

Decision: ---Select--- Reject H0 Fail to reject H0

Answer #1

Applying 2 way ANOVA:

Source of Variation |
SS |
df |
MS |
F |
P-value |
F crit |

Dose | 6.1250 | 1 | 6.1250 | 4.0758 | 0.0664 | 9.3302 |

Antidose | 16.9144 | 2 | 8.4572 | 5.6277 | 0.0189 | 6.9266 |

Interaction | 4.2233 | 2 | 2.1117 | 1.4052 | 0.2829 | 6.9266 |

Within | 18.0333 | 12 | 1.5028 | |||

Total | 45.2961 | 17 |

Antiote:

critical value =6.9266 ; test statistic = 5.6277

Fail to reject H0

**dose**:

critical value =9.3302 ; test statistic = 4.0758

Decision: Fail to reject H0

**Interaction**:

critical value =6.9266 ; test statistic =1.4052

Decision: Fail to reject H0

In a study of memory process, rats were first presented with a
fear-inducing stimulus on a learning task as soon as they stepped
across a line in a test chamber. Afterwards, the rats were divided
and given electrical stimulation either 50 or 150 milliseconds
after crossing the line. In addition, the rats differed in terms of
the area in which the stimulation electrodes were implanted in
their brains (Neutral Area, Area A, or Area B). Researchers were
interested in the...
