Answer 12

As cars passed a checkpoint, the following speeds were clocked and recorded.
Speed (mph): 55 62 61 54 68 72 59 61 70


16. What are the minimum, first quartile, median, third quartile, and maximum of the data set? Show your work.

Answer 13

First put the numbers in order:
54 55 59 61 61 62 68 70 72

The lowest number is the minimum. The highest is the maximum.

Find the number that is in the middle (you can lightly cross out the outer numbers)
The middle number is 61. That is the median.

Then find the middle of each half. Since these numbers are between 2 numbers, you average the numbers (add then dividde by 2).
55+59=114/2=57 This is the first quartile.
68+70=138/2=69 This is the third quartile.
