Sagot :
Let's break down what the question is asking and how we can arrive at the correct answer.
First, we shall interpret the details provided:
- The survey is of 150,000 residents in Lakeview who participate in the recycling program.
- Preferences for recycling pickups are categorized into two types: same day and separate days.
### Calculations and Breakdown:
1. Same Day Pickup Preferences:
- Newspaper: 108,000 residents prefer to have their newspaper recycling picked up on the same day.
- Plastic: 72% of the total residents prefer to have their plastic recycling picked up on the same day.
[tex]\[ \text{Plastic Same Day} = \frac{72}{100} \times 150,000 = 108,000 \text{ residents} \][/tex]
2. Separate Days Pickup Preferences:
- Newspaper: 42,000 residents prefer to have their newspaper recycling picked up on separate days.
- Plastic: 28% of the total residents prefer to have their plastic recycling picked up on separate days.
[tex]\[ \text{Plastic Separate Days} = \frac{28}{100} \times 150,000 = 42,000 \text{ residents} \][/tex]
### Solution Determination:
The question mentions that this survey is an example of what type of activity: describing data, collecting data, or making an inference?
- Describing Data: This involves summarizing and presenting existing data. The survey results fall into this category as it represents a summary of preferences among residents.
- Collecting Data: This would involve the active process of gathering new data from respondents. However, the data has already been collected and summarized.
- Making an Inference: This involves making predictions or generalizations based on the data. The question does not involve making predictions beyond the given preferences.
Given the above interpretations:
[tex]\[ \textbf{Answer: A. describing data} \][/tex]
Thus, this survey and its summary table are an example of describing data.
