Question

It has been suggusted that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 694 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below.

Number of Nights | Pre-retirement | Post-retirement | Total |

4−7 | 237 | 163 | 400 |

8−13 | 79 | 72 | 151 |

14−21 | 40 | 56 | 96 |

22 or more | 10 | 37 | 47 |

Total | 366 | 328 | 694 |

With this information, construct a table of estimated expected
values.

Number of Nights | Pre-retirement | Post-retirement |

4−7 | ||

8−13 | ||

14−21 | ||

22 or more |

Now, with that information, determine whether the length of stay is
independent of retirement using α=0.05α=0.05.

(a) χ2=χ2=

(b) Find the degrees of freedom:

(d) The final conclusion is

**A.** We can reject the null hypothesis that the
length of stay is independent of retirement and accept the
alternative hypothesis that the two are dependent.

**B.** There is not sufficient evidence to reject the
null hypothesis that the length of stay is independent of
retirement.
