difference in means of the i^{th} resample |

Sort the difference in means of the resamples in increasing order. *d*_{1} is the lowest number, *d*_{B} is the highest number.

Lower bound: *d _{l}* where =

Upper bound: *d _{u}* where =

For a one-sided case (only a lower bound or upper bound), use α instead of α/2.

When *l* or *u* are not integers, Minitab does a linear interpolation between the two numbers on either side of *l* or *u*. The formula is:

*d _{y}* +

For example, if *l* = 5.25, the lower bound equals d_{5} + .25(d_{6} - d_{5}).

Minitab does not display the confidence interval when or .

Term | Description |
---|---|

α | 1- confidence level/100 |

B | number of resamples |

d _{y} | the y^{th} difference when the data are sorted from least to greatest |

y | the truncated value of l or u |

z | l-y or u - y |
