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 702 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. With this information, construct a table of estimated expected values. Use two digits after the decimal: Now, with that information, determine whether the length of stay is independent of retirement using = 0.05. (a) x2= Use as many digits after the decimal as possible. (b) Find the degrees of freedom: (c) Find the critical value: Again, use as many digits after the decimal. (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 B. There is not sutficient evidence to reject the null hypothesis that the length of stay is independent of retirement. are dependent..
