Final answer:
To ascertain the number of install events accompanying meter exchanges in the previous year, one must review the utility company's records from that period. The analysis involves counting the meter exchanges and matching them with related install events to get a total count.
Step-by-step explanation:
To determine the number of install events for the previous year when a meter exchange occurred, it is essential to have access to the utility company's records for that year. These records would typically detail every instance of meters being exchanged and any subsequent installations that took place as a result. If you're inquiring about a specific utility company or geographic location, the data may vary, and you would need to refer to their system of record-keeping or transaction logs to obtain an accurate count.
To proceed with the analysis, you would first identify the time frame for the 'previous year.' Then, you would look through the operational or transactional records to count the number of meters exchanged. For each of those meters exchanged, you would match them with any related install events, such as installations of new meters or re-installation of existing ones. The total count of these matched entries would give you the number of install events for the previous year, associated with meter exchanges.
