   Question

   A book is randomly selected from a bookshelf. Which of the following characteristics of the book are continuous or discrete stochastic variables?

   I. Weight of the book (e.g., 2.3 pounds). II. Number of chapters in the book (e.g., 10 chapters). III. Width of the book (e.g., 8 inches). III. IV. The type of book (0 = hardback or 1 = paperback). IV. V. The number of typos in the book (e.g., 4 errors).

   
   
   1. FALSE: I, II and V are discrete stochastic variables.
   2. TRUE: I and III are continuous stochastic variables.
   3. FALSE: II, IV and V are continuous stochastic variables.
   4. FALSE: I, III and IV are continuous stochastic variables.
