Question 915797: The following are the annual incomes (in
thousands of dollars) for randomly chosen,
U.S. adults employed full-time:
27, 31, 33, 34, 35, 38, 39, 40, 40, 40, 41, 41, 42,
42, 44, 47, 49, 50, 51, 54, 63, 82, 90, 112.
(a) Which measures of central tendency do
not exist for this data set? Choose all that
apply.
1. Mean
2. Median
3. Mode
4. None of these measures
(b) Suppose that the measurement 112 (the
largest measurement in the data set) were
replaced by 153. Which measures of
central tendency would be affected by the
change? Choose all that apply.
1. Mean
2. Median
3. Mode
4. None of these measures
(c) Suppose that, starting with the original
data set, the smallest measurement were
removed. Which measures of central
tendency would be changed from those of
the original data set? Choose all that apply.
1. Mean
2. Median
3. Mode
4. None of these measures
(d) The relative values of the mean and
median for the original data set are typical
of data that have a significant skew to the
right. What are the relative values of the
mean and median for the original data set?
Choose only one.
1. Mean is greater
2. Median is greater
3. Cannot be determined
5. Graph the line.

a. data set has mean
(sum/24) = 48.5(rounded),
median = 41.5 (middle two numbers smallest to largest)/2 and
mode is 40(3 of them)
b. replacing 112 with 153...will change mean
c. removing smallest, mean and median will change
d. Mean is greater (skewed right)
