Give the hypothesis, critical value and Region, test statistic and conclude A nation-wide real estate chain is in the process of comparing townhouse prices in four citiesacross the country. It is, however, known that the area size of a townhouse is also a determiningfactor on price fixing and should be controlled by using blocks. Therefore, in each city, the sellingprices of a 90m^2, a 120 m^2, a 50^2, a 180m^2 and a 210m^2 townhouse are randomlyselected. The results are recorded to the nearest R1000 and are shown below:TownhouseSize m^290120150180210Bloemfontein660792100412481620Durban74077286010721524Port Elizabeth6927247889161176Johannesburg800784111213281784

Perform a hypothesis test to determine whether there is a difference in the mean attendance of teams between the two groups created in Part F. Use a 0.05 level of significance in your testing procedures. Hint: When calculating your pooled sample variance and your test statistic, assume the Top 10 data is sample 1 and the Bottom 10 data is sample 2. Decision Rule -t < or t > = REJECT H0 Value of Pooled Sample Variances Value of test statistic Decision: enter Reject or Do Not Reject Is there a difference in the mean attendance between the two groups assuming a 0.05 level of significance? Enter Yes or No. Another variable that can impact attendance is the team's win-loss record. Teams that are winning more games are thought to have increased attendance as fans prefer to see their home team "win" rather than "lose" (although for some teams such as the Chicago Cubs, this is not always an established relationship!).
