Question 3 options:

We use the normal distribution when we conduct a hypothesis test about a population mean. | |

We use the t-distribution when we conduct a hypothesis test about a population proportion. | |

Researchers get to choose the significance level. A few popular choices are 10%, 5% and 1%. However, it is not possible to choose 0%! | |

We use the normal distribution when we conduct a hypothesis test about a population proportion. | |

We use the t-distribution when we conduct a hypothesis test about a population mean. | |

The Rejection Region approach and the p-value approach always agree. Meaning, our conclusion concerning whether or not to reject Ho would be the same regardless of which method we use. |
