Final answer:
The question appears to be about service process times, likely in a college-level mathematics context pertaining to operations management or statistics. However, without the necessary context or precise information relating to the original question about door-to-device times, a definitive answer cannot be given.
Step-by-step explanation:
The subject of the question seems to be related to service operation metrics, specifically the time it takes for a process such as patient admission in a healthcare facility (guessing from context, as 'pts' could mean patients). However, without context, the exact meaning of 'door-to-device times' is not apparent. Hence, we will proceed with the assumption that we're dealing with service process times.
From the given information, it is unclear what the correct values are for direct arriving and transferring points. The information provided involves the average time between customer arrivals and wait times but does not specify door-to-device times for any type of arrival. Therefore, based on the information given and without additional context to link it to the question, it is impossible to confidently select a correct answer between options A, B, C, or D.
However, examples from the related information show calculations of expected arrival times and the understanding of probability and percentiles within this context, which are common elements in operations management and statistics - subfields of mathematics often covered in college courses.
