The results of a survey comparing the costs of staying one night in a full-service hotel (including food, beverages, and telephone calls, but not taxes or gratuities) for several major cities are given in the following table. Do the data suggest that there is a significant difference among the average costs of one night in a full-service hotel for the five major cities? Use a 0.05 level of significance and assume the population distributions are approximately normal with equal population variances.

Maximum Hotel Costs per Night ($)

New York	Los Angeles	Atlanta	Houston	Phoenix
308	261	320	200	260
260	268	275	233	308
301	225	257	244	256
237	312	298	201	282
199	328	298	252	243

Step 1 of 2 :

Compute the value of the test statistic. Round any intermediate calculations to at least six decimal places, and round your final answer to four decimal places.

Step 2 of 2: Draw a conclusion and interpret the decision. Fail or reject? Is there enough evidence?
