Final answer:
The standard delivery time for transcript orders cannot be determined from the provided information. However, context from the question suggests a focus on averages and distributions in the field of probability and statistics.
Step-by-step explanation:
The question asks about the standard delivery time for transcript orders unless they are expedited. None of the provided references directly answer this question, but they give context on different average times for various scenarios. For instance, the duration of a particular type of criminal trial has a mean of 21 days with a standard deviation of seven days, which is specified in reference 79 and 73.
With the information provided, it isn't possible to ascertain the correct choice between options A) 7, B) 14, C) 21, D) 30 for the regular delivery time for transcript orders. Additional information or context is needed to determine the standard time frame for transcript delivery. However, the question seems to be aiming at understanding averages and distributions, which is an essential aspect of probability and statistics in mathematics.
