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 719 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 8 13 14-21 244 77 36 22 or more 23 Total 380 33323 173 417 152 88 62 719 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 a = 0.01. (a) x2= - (b) Find the degrees of freedom: (c) Find the critical value: (d) The final conclusion is ○ A. There is not sufficient evidence to reject the null hypothesis that the length of stay is independent of retirement. O B. 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.
