Studdy Solution

STEP 1

Assumptions1. The ages of the people in the van are14,9,9,15,13, and31 years. . The mean age is calculated as the sum of all ages divided by the number of people.
3. The result should be rounded to the nearest tenth of a year.

STEP 2

First, we need to find the sum of all ages. We can do this by adding all the given ages together.
Sumofages=14+9+9+15+13+31Sum\, of\, ages =14 +9 +9 +15 +13 +31

STEP 3

Calculate the sum of all ages.
Sumofages=14+9+9+15+13+31=91Sum\, of\, ages =14 +9 +9 +15 +13 +31 =91

STEP 4

Now that we have the sum of all ages, we can calculate the mean age. The mean age is calculated by dividing the sum of all ages by the number of people.
Meanage=Sumofages/NumberofpeopleMean\, age = Sum\, of\, ages / Number\, of\, people

STEP 5

Plug in the values for the sum of all ages and the number of people to calculate the mean age.
Meanage=91/Mean\, age =91 /

STEP 6

Calculate the mean age.
Meanage=91/6=15.166666...Mean\, age =91 /6 =15.166666...

STEP 7

Now that we have the mean age, we need to round this to the nearest tenth of a year.
Roundedmeanage=15.2Rounded\, mean\, age =15.2The mean age of the people in the van is15.2 years.
