I want to know the answer to the following question:
What is the national average of high school diploma holding citizens?
All the background I'm provided with is that "Of the city's population over the age of 25, 53.8% (vs. a national average of 27.4%) hold a bachelor's degree or higher, and 91.9% (vs. 84.5% nationally) have a high school diploma or equivalent.". Is that enough to answer the question?
Answer: yes
