MEAN OF X = 16 MEAN OF Y = 6.57
Step-by-step explanation:
ARITHEMETIC MEAN = Arithemetic mean of numbers is defined as the ratio of the sum of all the numbers to to the total numbers.
It is abreviated as AM.
For a set of numbers, AM =
Where N is the total numbers in the set.
X 10,12,14,16,18,20,22 N = 7
AM =
AM = 16
Alternatively for X as all the numbers are evenly distributed hence the mean will be the central number of the set . this is only applicable for evenly distributed numbers.
Y 4,5,8,16,7,4,2 N = 7
AM =
AM = 6.57
