10)Two real estate companies, Century 21 and RE/MAX, compete with one another in a local market.The manager of the Century 21 office would like to advertise that homes listed with RE/MAXaverage more than 10 days on the market when compared to homes listed with his company. Thefollowing data shows the sample size and average number of days on the market for the twocompanies along with the population standard deviations.Century 21RE/MAXSample mean122 days144 daysSample size3630Population standard deviation32 days35 daysIf Population 1 is defined as RE/MAX and Population 2 is defined as Century 21, and using ΅0.10, the conclusion for this hypothesis test would be because the test statistic is10)=
