To solve this problem, let us first write out the values discretely from the plot made by Josh.
Thus, from the plot made by Josh, we can write out the numbers and the amount of times they occur, as follows:
0, 2, 2, 3, 4, 4, 5, 5, 6, 7, 7, 7, 8, 8, 8, 9, 10, 11, 11, 13
Minimum value= 0
Maximum value= 13
Median= (7 + 7)/2 = 14/2 = 7
First quartile = (4+4)/2 = 8/2 = 4
Third quartile= (8+9)/2= 17/2 = 8.5
Therefore, the correct answer is : Option C
