Final answer:
The percentage of employees who indicate tangible gifts as their preferred way of being appreciated is highest among manual laborers, followed by non-manual wage earners, mid-level managers, and executives.
Step-by-step explanation:
The question is asking about the percentage of employees who indicate tangible gifts as their preferred way of being appreciated and the percentage of employees who have them as their least valued language of appreciation. To answer this question, we need to refer to the given information about 1,050 randomly selected adults and their preferences for trucks based on their job roles.
According to the information provided, 82% of manual laborers preferred trucks, 62% of non-manual wage earners preferred trucks, 54% of mid-level managers preferred trucks, and 26% of executives preferred trucks. Since the question is about the preference for tangible gifts, we can infer that the percentage of employees who indicate tangible gifts as their preferred way of being appreciated is highest among manual laborers, followed by non-manual wage earners, mid-level managers, and executives. Therefore, the correct answer is (a) Preferred: 10%, Least Valued: 30%.
