(1 point) 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 717717 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
4−74−7 245245 171171 416416
8−138−13 8282 6868 150150
14−2114−21 3535 6060 9595
2222 or more 1616 4040 5656
Total 378378 339339 717717


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

Number of Nights Pre-retirement Post-retirement
4−74−7
8−138−13
14−2114−21
2222 or more


Now, with that information, determine whether the length of stay is independent of retirement using α=0.01α=0.01.

(a)  χ2=χ2=

(b) Find the degrees of freedom:

(c) Find the critical value:  

(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.
