The Lee family is looking to buy a house in one of two suburban areas just outside a major city, and the air quality is a top priority for them. One suburb advertises use of hybrid cars and solar panels, while the other area focuses on its convenient bus routes and availability of Hummer dealerships. Is the mean or median the better measure to use for deciding which area has better air quality? (Hint: these populations are skewed.)A. The median, because it is not affected by outliers.
B. The median, because it is less biased by skewness being dependent on the middle score.
C. The mean, because it is always the best measure of central tendency in any population.
D. The mean, because it represents the balance of the distribution.

The answer would be B. The median, because it is less biased by skewness being dependent on the middle score.

Step-by-step explanation:

Because the median is the average including all the numbers in the data set which would be part of the dependent variable times the length of the base of a independent variable which would not change the independent variable because only the independent variable changed the dependent variable.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
