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 S 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. z-Test: TWO Sample for Means Krown Variance Hypothesized Mean Di Terence Critical PIZ=t) twctail Critical o New O , teans 125 -1.774 003" 1.28155157 00714 1.64485363 t-Test: Paired Two Sample for Means 'lean Variance Pearsm Correlation Hypthesized Mean Difference one-tail t Critical one-tail t Critical two-tail 162990476 1811.54879 -1.5516149 0.0578 1.29943888 0.1156 167722a2 t-T6t: Two-SWe Assuming VarOnces V Once Observ* On s Hvpotheized Mean df t Stat t Critical me-tail Critical two-tail e-Te* Two for Sane Prom'tbn Hypothesized Difference t Critkal ore-tall Atlanta New 1629.90476 125 .tsst6t49 00578 1.29943888 0.1156 $7727 Atlanta New Ode-ans 0.1629 0.1811 -20249019 0.02143872 1.64485363 004287 'u What is (are) the independent variable(s) for this analysis? o O O o o Hotel prices Atlanta and New Orleans Retailers and Manufactures sally Private label brands
