Calculate standard deviation
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?
(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

what is the variance?
what is the standard deviation, rounded to the nearest whole number?
