Answer 4

**ANSWER: A mean = –28.5, median = –29.1, mode = –49, range = 40

First put them in order:
- 49, - 49 , - 43 , -39 , -18, -14, -12, -9
Add the two middle numbers -39 and -18, it equals -57
Divide - 57 and 2, it equals - 28.5 <--- MEAN

Second add all the numbers together, it equals - 233, then divide by 8, which equals
- 29.1 <---MEDIAN

MODE is the number that happens most, which is -49 <--- MODE

The range is -49 - ( -9 ) = - 40 <-----RANGE
