Answer:
40% of the people are above the average age of 35.
Explanation:
We have to find the percent of people above the average age, Hence we have to first find the average age of the group.
To find the average age we have to use the formula
Average= sum of all elements ÷ no of elements
∴Average= (34+27+36+18+15+72+67+12+24+45)÷ 10
= 350÷ 10
= 35
∴35 is the average age of the people in the group.
Now we have the number of people above 35. There are 4 people above the age 35.
to find the percentage we have to use the formula,
Percentage = (no. of people/total no of people) × 100
= (4/10) × 100
= 0.4 ×100
= 40
∴40% of the population is above the average age, which is 35.
