Introduction

The data in the table represents the percentage of a country's population aged 20 years or older who do not have a high school diploma. This information is crucial in understanding the educational landscape of a particular country and can be used to inform policy decisions related to education. In this article, we will analyze the data in the table and complete parts (a) through (c).

The Data in the Table

Age, ${ a }$	20	30	40	50	60
Percentage	15	20	25	30	35

Part (a)

Calculate the percentage of population aged 20-30 years who do not have a high school diploma

To calculate the percentage of population aged 20-30 years who do not have a high school diploma, we need to find the difference between the percentage of population aged 30 years and the percentage of population aged 20 years.

The percentage of population aged 30 years who do not have a high school diploma is 20%. The percentage of population aged 20 years who do not have a high school diploma is 15%.

Therefore, the percentage of population aged 20-30 years who do not have a high school diploma is:

20% - 15% = 5%

Calculate the percentage of population aged 40-50 years who do not have a high school diploma

To calculate the percentage of population aged 40-50 years who do not have a high school diploma, we need to find the difference between the percentage of population aged 50 years and the percentage of population aged 40 years.

The percentage of population aged 50 years who do not have a high school diploma is 30%. The percentage of population aged 40 years who do not have a high school diploma is 25%.

Therefore, the percentage of population aged 40-50 years who do not have a high school diploma is:

30% - 25% = 5%

Calculate the percentage of population aged 50-60 years who do not have a high school diploma

To calculate the percentage of population aged 50-60 years who do not have a high school diploma, we need to find the difference between the percentage of population aged 60 years and the percentage of population aged 50 years.

The percentage of population aged 60 years who do not have a high school diploma is 35%. The percentage of population aged 50 years who do not have a high school diploma is 30%.

Therefore, the percentage of population aged 50-60 years who do not have a high school diploma is:

35% - 30% = 5%

Part (b)

Determine the age group with the highest percentage of population without a high school diploma

To determine the age group with the highest percentage of population without a high school diploma, we need to compare the percentages of population without a high school diploma for each age group.

The age group with the highest percentage of population without a high school diploma is the 60-year age group, with a percentage of 35%.

Determine the age group with the lowest percentage of population without a high school diploma

To determine the age group with the lowest percentage of population without a high school diploma, we need to compare the percentages of population without a high school diploma for each age group.

The age group with the lowest percentage of population without a high school diploma is the 20-year age group, with a percentage of 15%.

Part (c)

Calculate the average percentage of population without a high school diploma for all age groups

To calculate the average percentage of population without a high school diploma for all age groups, we need to add up the percentages of population without a high school diploma for each age group and divide by the number of age groups.

The average percentage of population without a high school diploma for all age groups is:

(15 + 20 + 25 + 30 + 35) / 5 = 25%

Therefore, the average percentage of population without a high school diploma for all age groups is 25%.
