Answer:
Mean = 13,155.6
Median = 12,700
Mode: No mode
Explanation:
Gina drove her car over first five years.
12,700 15,478 12,675 11,850 13,075
We need to find mean, median and mode
Mean: It is value of sum of all observation over number of observation.
Mean

Mean

Mean = 13,155.6
Median: It is middle value of the arrange data.
First we arrange the given data into acceding order.
11,850 12,675 12,700 13,075 15,478
Total number of data = 5
Middle term = 3
Median = 12,700
Mode: It is value of the observation which repeated maximum number of times.
Here no value repeat more than one time.
Hence, No mode for this data
