During the soccer World Cup in 2010 attendance gurm [in thousands of people) of people watching games at four of the World Cup venues were recorded for some of the games at each stadium, shown as follows: Stadium Attendance 1'; (Ya:- - it? n. (Y; 1e") 2 Gwen Point 3.9 7.2 3.1 7.1 6.7 18.16 0.06 Soccer Cit},r 6.6 6.9 8.2 8.3 2.30 4.05 Ellis Park 5.5 7.3 7.2 6.3 1.94 0.04 Nelson Mandela 4.2 6.9 4.1 5.8 5.45 (53.19I (3} Explain how a. bootstrapping approach might be used to test the: hypothesis of no differences between mean crowd attendance at the four stadiums. (b) Such a bootstrapping approach was applied, based on 2000 bootstrap replications. For each replicationJ the SSE1 SST and the FIatios were calculated. The Fratios were sorted from smallest to largest, and the following are a selection of the observed values: Sample No: 50 100 500 1000 1500 1900 1950 2000 Fratio 0.15 0.23 0.63 1.18 2.03 4.33 5.77 14.96 What conclusion should be drawn about any dj'erenoes between the stadiums
