# Question: 1 f samples of 100 for a process are taken...

###### Question details

1. f samples of 100 for a process are taken and *p* is
0.15, the upper and lower control limits for a 3-sigma
*p*-chart are

a |
UCL = 0.322, LCL = 0.000 |

b |
UCL = 0.190 , LCL = 0.010 |

c |
UCL = 0.257, LCL = 0.043 |

d |
UCL = 0.045, LCL = 0.005 |

2.

In an Excel spreadsheet for a *p*-chart, if the total
number of defectives for 20 samples of 100 observations each is in
cell F26, the Excel formula for *p* is

a |
=((F26)*(20))/100 |

b |
=((F26)*(100))/20 |

c |
=(F26)/(20) |

d |
=(F26)/((20)*(100)) |

3. In an Excel spreadsheet for a *c*-chart, if the
population process average for 20 samples, *c*, is in cell
H4, the Excel formula for the upper control limit is

a |
=H4+SQRT(3*H4) |

b |
=H4+3*SQRT(H4) |

c |
=H4+3*SQRT((H4*(1-H4))/(100)) |

d |
=H4+3*SQRT(H4/20) |
