Also, the results don't show at all that "more Americans went to the library than to the movies" but rather that Americans went more to the library than to the movies (on average), which is not very surprising given that only one of them is free.
In other words, if 100 Americans went to the movies once, and 1 American went to the library 101 times, the results would still rank libraries higher than movies despite it being obviously not true that "more Americans went to the library than to the movies."
