A nutritionist wants to collect data on how much water the average American drinks per day. She has the following ideas for how she could obtain a sample: a. Ask the first 20 adults who arrive at a grocery store after 10:00 a.m. about the average amount of water they consume each day. b. Every 30 minutes, ask the first adult they see exercising outdoors about the average amount of water they consume each day. 1. Would the different methods for selecting a sample lead to different conclusions about the population? 2. Which of the methods listed would be the most likely to produce samples that are representative of the population being studied? 3. Can you think of a better way to select a sample for this situation
