Task: The Number of Hispanics (Latinos) in the United States

Consider the population of Hispanic (Latino) people in the United States, according to the 2010 US Census. Examine the data for the 2010 US Census in the 11a-10 Unit Activity Data Set 1 spreadsheet.

1. [5 points] How do the columns titled "Number" and "% of Total Population" relate to the columns titled "Total"?



Answer :

To solve this question and understand the relationship between the columns titled "Number" and "% of Total Population" with the "Total" column in the context of the Hispanic (Latino) population data from the 2010 US Census:

1. Number (Hispanic Population): This column represents the absolute count of Hispanic (Latino) individuals within each specific geographic region or state.

2. % of Total Population: This column indicates the percentage that the Hispanic (Latino) population constitutes of the total population in each specific geographic area or state.

3. Total (Total Population): This column represents the total population of the given geographic region or state.

We can derive the relationship between these columns using basic mathematical reasoning:

### Step-by-Step Analysis:

- Step 1: Understanding the "Number" Column:
- This column gives the actual number of Hispanic (Latino) people in a region.
- For example, if the "Number" column for Region A shows 50,000 Hispanics, this means there are exactly 50,000 Hispanic (Latino) individuals in Region A.

- Step 2: Understanding the "% of Total Population" Column:
- This column provides the percentage of the total population that is Hispanic (Latino).
- For example, if Region A has a "% of Total Population" of 10%, it means Hispanics (Latinos) make up 10% of the entire population in Region A.

- Step 3: Understanding the "Total" Column:
- This column gives the total number of people (the whole population) living in the region.
- For example, if Region A has a "Total" population of 500,000 people, there are 500,000 individuals living in that region, irrespective of ethnicity.

### Mathematical Relationship:

The relationship between these columns can be expressed through the formula:

[tex]\[ \text{Number} = \left( \frac{\% \text{ of Total Population}}{100} \right) \times \text{Total} \][/tex]

### Example:

Imagine you have data for a specific region:

- Total population of the region = 500,000 (from the "Total" column)
- Percentage of the total population that is Hispanic (Latino) = 10% (from the "% of Total Population" column)

Using the relationship,
[tex]\[ \text{Number} = \left( \frac{10}{100} \right) \times 500,000 = 0.10 \times 500,000 = 50,000 \][/tex]

Therefore, the "Number" of Hispanic (Latino) individuals in this region would be 50,000.

### Conclusion:

In summary, the "Number" column represents the Hispanic (Latino) population in absolute terms, the "% of Total Population" column indicates what portion of the total population this number represents as a percentage, and the "Total" column is the overall population figure for the region. The values in the "Number" column can be derived by multiplying the total population by the percentage (as a decimal) indicated in the "% of Total Population" column.
