Answer :
Final Answer:
The percentage of repeat customers at a certain Starbucks on Saturday mornings is based on a sample.
Explanation:
This data represents a sample. A sample is a subset of a larger population, in this case, the customers at a specific Starbucks on Saturday mornings. To calculate the percentage of repeat customers, you wouldn't need to survey every single customer; instead, you can collect data from a representative group (the sample) and use it to make inferences about the entire population of Saturday morning customers at that particular Starbucks.
In this context, the sample might involve surveying or tracking a portion of customers over several Saturday mornings to determine the percentage of those who return. The findings from this sample can then be used to estimate the proportion of repeat customers in the broader population, which includes all customers visiting that Starbucks on Saturday mornings.
Sampling methods play a crucial role in statistical analysis and research. Different sampling techniques can be used to ensure that the sample accurately represents the population it's drawn from, and the choice of sampling method depends on the research objectives and available resources.
