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 deviation?
a. (225)² + (-425)² + (-275)² + (325)² + (75)² + (-75)² = 423,750b. (650)² + (-150)²+(-600)² + (250)² + (150)² + (-300)² = 980,000c. (250)² + (-400)² + (-250)² + (350)² + (100)² + (-50)² = 420,000
