what are the mean,median ,mode and range of the data set given the altitude of lakes in feet -11, -28, - 17, -25, -28, -39, -6, and -46

Answer:Mean=-21.5Median=-26.5Mode=-28Range= -6 to-46Step-by-step explanation:Arranging the numbers given either in ascending or descending order. In this case, I used descending order as follows-6-11-17-25-28-28-39-46Mode is the number that occurs more than others. In this case, only -28 appears twice hence it is the modeThe 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=-172Mean=-172/8=-21.5The 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=-26.5The range of numbers id from -6 to-46 as arranged above
