10: 10; 20; 10; 50: 20, 10050; 50: 10: 50
20; 100; 50; 20: 10; 10; 50; 100: 20
1. calculer la proportion des scores de julie valant 10
points.
2. parmi les scores de julie inférieurs ou égaux à 50,
calculer la proportion des scores valant 10 points.
3. construire le tableau des fréquences cumulées
croissantes.
4. julie pense qu'au moins un quart de ses scores sont
supérieurs à 50. a-t-elle raison ?
