Assume a researcher is interested in the effect of weight on a

number of adverse events in his new clinical trial. Assume the

following table represents the weights (kg) for a SRS of

individuals in both arms of the study.

Placebo |

76.5 |

64.7 |

67.8 |

65.2 |

74.6 |

80.1 |

64.8 |

Intervention |

80.7 |

78.6 |

76.4 |

78.3 |

A) Calculate the standard error for the difference in weight

between the two arms of the study.

B) Calculate the pooled standard error for the difference

assuming equal variances.
