MTN is conducting research to understand the satisfaction level of its customers. With a customer base of 1 million users, MTN recognises the need to select a representative sample for their study. A team of researchers is tasked with narrowing down their focus. After careful consideration, they randomly select 5,000 customers from various regions and demographic backgrounds. This means that every MTN user has a chance of being chosen to be part of the sample. The selected sample includes long-term subscribers and new users, ensuring a comprehensive representation of MTN's customer base. By analysing the feedback and opinions of this diverse group, MTN aims to gain valuable insights into their customers' satisfaction levels and make informed decisions to enhance their services.
