For Question 11, the optimum work - height can vary depending on many factors and 1750 mm is not a universal optimum, so it's false. For Question 12, it's stated points are awarded for any answer as the book is unclear. For Question 13, in job design, to ensure a good fit for the majority, both the upper and lower percentiles of people (extremes) are often excluded to account for typical physical and other capabilities.

Answer:

Question 11: False
Question 12: (No matter True or False as points are awarded for any answer)
Question 13: III. exclude both the upper and lower percentiles
