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 718 travelers were asked how long they stayed on a typical trip The observed results of the study are found below. You may round all answers for this problem to the nearest hundredth. Grades Problems Number of Nights Pre-retirement Post-retirement Total 401 155 100 62 718 8 13 14 -21 22 or more Total 236 85 40 25 386 165 70 60 37 332 Problem 3 X Problem 5 Problem 6 Problem 7 Problem 9 Problem 10 Problem 11 With this information, construct a table of estimated expected values. Use two digits after the decimal. Number of Nights Pre-retirement Post-retirement 8- 13 14 21 22 or more 215.58 83.33 53.76 33.33 185.42 71.67 46.24 28.67 Now, with that information, determine whether the length of stay is independent of retirement using a 0.05. (a) 2-16.374 iUse three digits after the decimal (b) Find the degrees of freedom: 3 (c) Find the critical value: 16.391 Try using all the digits Minitab will give you. 4:29 PM Type here to search

Explanation / Answer

Degrees of freedom = (r - 1)*(c - 1) = (4 - 1)*(2 - 1) = 3

Significance level = 0.05

Hence,

Critical value = 7.8147279
