+1982 number of data values: 2105
sum of the data values: 1008.08
Calculate the average (arithmetic mean) from the given number of data values and the sum of the data values.(rounded to the nearest tenth)
A) 0.4
B) 0.5
C) 0.7
D) 2.1
E) 5.0
B)0.5
Mean=sum of data/no. of data
Eg.
Find the mean of A,B = A+B (Their sum)/(2(Their number))
So the question already gave you the number of data which is 2105
and the sum of the data which is 1008.08
just apply the formula
1008.08/2105=0.47.... rounded to the nearest tenth would be 0.5 which is option B
B)0.5
