b) The proportion of books in the local public library that are novels is higher than the proportion of books in the university library that are novels


c) The average price of wool jackets in New York City is lower in the summer than in the winter.


d) The proportion of students who receive A grades from Professor Harrington is the same or higher than the proportion of students who receive A grades from Professor Cantor.
