1 | ```
lengthATW(n, alp, h, a, b)
``` |

`n` |
- Number of trials |

`alp` |
- Alpha value (significance level required) |

`h` |
- Adding factor |

`a` |
- Beta parameters for hypo "p" |

`b` |
- Beta parameters for hypo "p" |

Evaluation of approximate and adjusted method based on a t_approximation of the standardized point estimator using sum of length of the *n + 1* intervals

A dataframe with

`sumLen` |
The sum of the expected length |

`explMean` |
The mean of the expected length |

`explSD` |
The Standard Deviation of the expected length |

`explMax` |
The max of the expected length |

`explLL` |
The Lower limit of the expected length calculated using mean - SD |

`explUL` |
The Upper limit of the expected length calculated using mean + SD |
