Question
(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 714 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below. Number of Nights Pre-ret Post-ret 4-7 8 -13 14-21 22 or more Total 169 69 59 39 336 ota 410 154 93 57 714 241 85 34 378 With this information, construct a table of estimated expected values. ber of N Post-retirement 8-13 14-21 Now, with that information, determine whether the length of stay is independent of retirement using = 0.01 (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.Explanation / Answer
a)
TS = 26.38422
b)
df = 3
c) critical value = 7.82
d) A) reject the null
