A contractor records the areas, in square feet, of a small sample of houses in a neighborhood to
determine data about the neighborhood. They are:
2,400; 1,750; 1,900; 2,500; 2,250; 2,100
Which of the following represents the numerator in the calculation of variance and standard deviati
(225)2 + (-425)2 + (-275)2 + (325)2 + (75)2 + (-75)2 = 423,750
(650)2 + (-150)2 + (-600)2 + (250)2 + (150)2 + (-300)2 = 980,000
✓ (250)2 + (-400)2 + (-250)2 + (350)2 + (100)2 + (-50)2 = 420,000
