Answer
Brief Explanations:
- a. The weight of a hamburger can take on any value within a range (e.g., 100.5 grams, 100.55 grams), so it is a continuous random variable.
- b. The last - book read is a non - numerical and non - probabilistic outcome, so it is not a random variable.
- c. The number of runs scored in a baseball game can only be whole numbers (0, 1, 2,...), so it is a discrete random variable.
- d. The number of textbook authors eating a meal can only be whole numbers (0, 1, 2,...), so it is a discrete random variable.
- e. The number of statistics students doing their homework can only be whole numbers (0, 1, 2,...), so it is a discrete random variable.
- f. The number of home runs in a baseball game can only be whole numbers (0, 1, 2,...), so it is a discrete random variable.
Answer:
