Answer:
Mean=-21.5
Median=-26.5
Mode=-28
Range= -6 to-46
Explanation:
Arranging the numbers given either in ascending or descending order. In this case, I used descending order as follows
-6
-11
-17
-25
-28
-28
-39
-46
Mode is the number that occurs more than others. In this case, only -28 appears twice hence it is the mode
The mean is given by adding all the numbers and dividing by the frequency.
The sum of numbers will be -6+-11+-17+-25+-28+-28+-39+-46=-172
Mean=-172/8=-21.5
The median is the number that appears in the middle after arranging the numbers in descending order as above. In this case, two numbers appear in the middle, that is -25 and -28 hence median -25+-28/2=-26.5
The range of numbers id from -6 to-46 as arranged above
