Question 185968: you trace a frequency histogram of a distribution of x-values onto a uniformly thick sheet of plastic and cut it out. Which statements A,B,C, or D is true?
A. statements 1 and 3 are correct
b. statements 1 and 4 are correct
c. statements 2 and 3 are correct
d. statements 2 and 4 are correct
1. if the data are right-skewed, the median will be located to the right of the mean
2. if the data are right-skewed, the mean will be located to the right of the median
3. the median is the value of x at which the histogram balances, and the mean is the value of x that is larger than (or equal to) half of the x-values.
4. the mean is the value of x at which the histogram balances, and the median is the value of x that is larger than (or equal to) half of the x-values.

1. if the data are right-skewed, the median will be located to the right of the mean
Ans: True
------------------
2. if the data are right-skewed, the mean will be located to the right of the median
Ans: False

4. the mean is the value of x at which the histogram balances, and the median is the value of x that is larger than (or equal to) half of the x-values.
Ans: True
-------------------------------
Comment:
You can see this if you do a histogram and a whisker chart of a small set
of data that is skewed to the right, like 1,2,2,3,3,3,4,4,100
