Math Problem Statement
A study relating to the amount of time spent (in minutes) by a selected number of customers in a store was conducted on a particular Saturday. On that Saturday, a total of 12 234 customers visited the store. The time data is provided for these customers. The task involves identifying the sample and population size, stages of data handling, identifying outliers, and calculating quartiles.
Solution
The image you uploaded contains a set of mathematical problems related to statistics, specifically analyzing a dataset on the time spent by customers in a store. The tasks require working with concepts such as sample size, population size, outliers, and calculating quartiles.
I can help you solve the following:
- 3.2.1: Write down the number of customers representing the sample size and the population size.
- 3.2.2: Choose the correct stage of the data handling process.
- 3.2.3: Explain why 127 is considered an outlier.
- 3.2.4: Calculate the upper quartile (Q3) and verify if the outlier value was removed.
Let's proceed with each of these one by one. Would you like to start with a specific one, or should I solve them step-by-step for you?
