My best guess is C

Answer 2

what are your guesses?

Answer 3

The mean of a data set is sensitive to extreme scores.

The data here:

Jennifer sold 5 cars. The selling prices were $16,500; $32,500; $32,600; $35,000; and $35,100.

has a 16,500 data point that is much lower than the other 4.

I would use the median to represent this data set.
