Final answer:
The question focuses on calculating percentages for various categories within a given population, using division and multiplication. It also touches on the presentation of this information through graphs for clear communication of statistical data.
Step-by-step explanation:
This question is about calculating percentages of customers or members of different categories using the given data. To calculate a percentage, divide the number of individuals in a category by the total number of individuals, and then multiply by 100. For instance, if a hair styling salon has 1,177 clients and we want to know what percentage of them fall into a certain category (e.g., long-term clients), we would divide the number of long-term clients by 1,177 and then multiply by 100 to get the percentage. It's important to present this data clearly, often in the form of a bar graph or pie chart, to convey the population percentage of each category effectively.
For the specific exercises mentioned, it appears we lack adequate context or specific data to calculate percentages. However, the examples illustrate how real-world scenarios like a ballet instructor tracking student progression, car salespersons' weekly sales, and opinions on government funding for day care can be represented and analyzed statistically. Constructing a bar graph and calculating population proportions are practical applications of the data.
