(1 point) it has been suggusted that the highest prionty of retirees is travel Thus, a studiy was conducted to imvestigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 700 travelers were asked how long they stayed on a typlical trip. The observed results of the study are found beiow With this intormation, construct a table of estimated expected values Now, with that information, determine whether the length of stay is independent of retrement using a=0.01 (a) x2= (b) Find the degrees of freedom: (c) Find the citical value: (d) The final condisish is A. We can rejoct the null hypothesis that the length of stay is independent of refirement and acoept the alternative hypothesis that the two are dependent. B. There is not sumicicent evidence to refect the nid typoheshs that the length of stay is independent of retrement.
