Instructions: Answer all questions to get your test result.
1) The advertised rents for five apartments were $650, $650, $740, $1650, and $820. Which value best describes the monthly rents? Explain. mean = $902, median = $740, mode = $650
A
none of the above
B
The median best describes the rents because most of the rents were near $740.
C
The mean best describes the rents because $902 is the average rent.
D
The mode best describes the rents because $650 was the rent seen most often.

mean = 6.8, median = 5, mode = 8
B
mean = 7.5, median = 8, mode =4
C
mean = 6.8, median = 5, mode = 4
D
mean = 7.5, median = 5, mode = 4

10) Over the first five years of owning her car, Gina drove about 12,700 miles the 1st year, 15,478 miles the 2nd year, 12,675 the 3rd year, 11,850 the 4th year, and 13,075 the 5th year. which one will best predict how many miles Gina will drive the 6th
A
mean = 13,156; median = 12,700; no mode; the mean is the best choice because it is representative of the entire data set.
B
mean = 13,156; median = 12,700; mode = 3,628; the median is the best choice because it is not skewed by the high outlier.
C
mean = 13,156; median = 12,700; no mode; the median is the best choice because it is not skewed by the high outlier.
D
mean = 12,700; median = 13,156; no mode; the mean is the best choice because it is representative of the entire data set.
