Explanation:

To solve this, we match each example to the correct statistical vocabulary:

1. "The list of times for the 41 customers who left the bank": This is the collected values (data) from the sample. → d. Data
2. "The 41 customers that the manager observed leave": This is a subset of the population (all customers) studied. → e. Sample
3. "The length of time a customer waits before leaving the bank": This is the characteristic being measured (a variable). → f. Variable
4. "The average length of time that the 41 customers waited before leaving the bank": This is a numerical summary (statistic) from the sample. → a. Statistic
5. "The average length of time that all customers will wait before leaving the bank": This is a numerical summary (parameter) for the entire population. → c. Parameter
6. "All of the bank’s customers": This is the entire group of interest (population). → b. Population

Answer:

• The list of times for the 41 customers who left the bank: d. Data
