would you expect a positive, a negative, or no association between the number of hours of daylight during a day and the number of hours of darkeness?

Generally, a negative association. When one is increasing, the other is decreasing, except in the very Northern or Southern latitudes where there is no sunrise or sunset for half the year.

All of the hours of a day are either daylight or darkness. In the Northern Hemisphere we have long nights and short days in the winter. We have short nights and long days in the summer.
What kind of association is this?

A Negative Association?
