The difference in percentage of youngest and oldest age groups is 15.4%

<h3>The percentage from 11 to 20</h3>

Start by calculating the total number of people, as follows

People = 102 + 36 + 66 + 150 + 78 + 60 + 90 + 11 + 9

Evaluate

People = 602

The number of people in the age group 11 to 20 is:

Group = 36

So, the percentage is

Percentage = 36/602

Percentage = 6.0%

Hence, the percentage from 11 to 20 is 6.0%

<h3>The percentage from 31 to 40</h3>

The number of people in the age group 31 to 40 is:

Group = 150

So, the percentage is

Percentage = 150/602

Percentage = 24.9%

Hence, the percentage from 31 to 40 is 24.9%

<h3>The percentage from 71 to 80</h3>

The number of people in the age group 71 to 80 is:

Group = 11

So, the percentage is

Percentage = 11/602

Percentage = 1.8%

Hence, the percentage from 71 to 80 is 1.8%

<h3>The lowest percentage</h3>

This is the percentage of age group 81 to 90

And, the percentage is

Percentage = 9/602

Percentage = 1.5%

Hence, the lowest percentage on the chart is 5%

<h3>The percentage from 51 to 60 and 61 - 70 combined</h3>

The number of people in the age group 31 to 70 is:

Group = 60 + 90 = 15-

So, the percentage is

Percentage = 150/602

Percentage = 24.9%

Hence, the percentage from 51 to 60 and 61 - 70 combined is 24.9%

<h3>The difference in percentage of youngest and oldest</h3>

The youngest is 0 to 10 and the oldest is 81 to 90.

The number of people in these age groups are:

Youngest = 102

Oldest = 9

The difference is

Difference = 102 - 9

Difference = 93

So, the percentage is

Percentage = 93/602

Percentage = 15.4%

Hence, the difference in percentage of youngest and oldest is 15.4%
