To explain: If the sample statistics obtained can be used to generalize for the population.
The statistics show that the dealership is achieving a high level of customer satisfaction and it can be used to generalize for the overall population.
Given:
A customer satisfaction survey is conducted by selecting 500 customers randomly from a list of 5000 new customers in the last year. Among the 500 surveys sent 300 of them are answered.
