Final answer:
True, a medical facility must understand its target market's characteristics, including demographics, to develop an effective marketing plan.
Step-by-step explanation:
It is true that a medical facility should determine the characteristics of a typical member of the target market before developing a marketing plan. Understanding the target market is crucial in creating a plan that is tailored to the market's needs and preferences. A detailed market analysis often includes demographic information such as age, weight, gender, and health status, as these characteristics affect healthcare needs and choices. In contrast, physical shapes and dimensions are more relevant to product design than to market analysis.
