Data were collected from librarians about their reading habits and job experience. The results were used to calculate the model ŷ = 3.84x + 9.85, where x represents the number of years working as a librarian and ŷ represents the predicted number of books read per year. Interpret the slope of the model in the context of the problem.  Approximately 10 librarians read between 3 and 4 books each.  Approximately 4 librarians read 10 books each. For every additional year working, librarians are predicted to read between 3 and 4 more books per year.  For every additional year working, librarians are predicted to read more than 9 more books per year.
