Sally, a recent graduate of the University of Arkansas, accepted a position as an event coordinator for a major marketing firm. Sally's first task is to organize a convention of retailers and manufactures of private label store brands. She wants to select a city that has low hotel cost. She has narrowed her choice to Atlanta and New Orleans. She collects sample data on 25 hotels in both cities for a 5 night stay. Since there is a vast amount of historical data for hotel prices in both cities, she finds the known variance to be $125 in Atlanta and $150 in New Orleans. Can she conclude that there is a difference in hotel cost between the two cities? If there is a difference, she will use that information and select the city with the lower cost. The level of significance is .10. If appropriate, you should assume unequal variances. 44. Which of the following is the hypothesis test that Sally should use? a. Ho: H Atlanta - H New Orleans 2 0; HA: H Atlanta - H New Orleans
