Hey can you please check all answers and also give me the answer for the table fill in

Problem 5. (2 points) CO LL Blue Red White Yellow_or_Orange It has been suggusted that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the 52.95 56.99 52.88 48.54 length of stay of a trip for pre- and post-retirees. A sample of 687 travelers were asked how long they stayed on a typical trip. The 49.08 56.76 46.34 44.8 observed results of the study are found below. may round all answers for this problem to the nearest thoudanth. 52.33 54.81 51.99 45.47 Number of Nights Pre-retirement Post-retirement Total 54.3 56.62 48.21 46.7 4-7 234 170 404 59.64 54.98 52.8 46.69 8 - 13 146 49.28 58.77 53.07 49.88 14 - 21 50.77 52.74 56.27 42.43 50.2 52.9 50.75 47.88 22 or more 362 48.97 54.67 50.88 48.6 Total 325 687 46.46 57.74 47.97 45.19 55.72 47.29 49.6 (Worth ~20%) With this information, construct a table of estimated expected values. Use at least one digits after the decimal. 50.63 53.25 48.54 Number of Nights Pre-retirement Post-retirement 49.52 52.9 52.59 52.47 51.3 41.78 8 - 13 48.46 55.17 47.66 14 - 21 52.55 54.75 49.26 45.84 49.22 22 or more 48.46 42.51 50.46 Now, with that information, determine whether the length of stay is independent of retirement using a = 0.01. 48.38 50.19 (a) (Worth ~20%) Xiest Statistic = 7.119 Use at least three digits after the decimal. 53.81 50.53 (b) (Worth ~20%) Find the degrees of freedom: 3 (c) (Worth ~20%) Find the critical value when the significance level is 1 %: 5.841 |Use at least three digits after the decimal. [Hint: Critical value is the value of the test statistic, which defines the threshold of statistical significance in a statistical test.] (d) (Worth ~20%) 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. 33 O B. There is not sufficient evidence to reject the null hypothesis that the length of stay is independent of retirement. 34
