A meteorologist has measured the amount of rain in four cities for the last six months. She wants to know if there are different amounts of rain in the four cities. The table shows the data.

City 1	City 2	City 3	City 4
68	119	70	61
93	116	68	54
123	101	54	59
83	103	73	67
108	113	81	59
122	84	68	70

Conduct a Kruskal–Wallis test to see if there is a significant difference in the amount of rain in the four cities. Use aχ²approximation. Select the appropriate critical value (CV), test statistic (TS), and decision. (Useα=0.025.)

▸

CV = 7.3778, TS = 14.04, rejectH₀

▸

CV = 9.2103, TS = 15.98, rejectH₀

▸

CV = 9.3484, TS = 15.98, rejectH₀

▸

CV = 9.3484, TS = 9.22, fail to rejectH₀
