Answer:

C

Step-by-step explanation:

min and max are correctly the same for all 4 answers.

we have 10 data points, so, the median is the mean value between the 2 middle numbers, 19 and 22 : 20.5.

ah, it can be only C or D.

Q1 is the median of the lower half of data points (13 out of 11, 12, 13, 17, 19). and Q3 is the median of the upper half of data points (29 out of 22, 24, 29, 33, 38).

so, C is correct.
