SAMPLING PRACTICE Step 1: Place the 25 rectangles in a bag and shake thoroughly. Then, without looking in the bag, draw five rectangles from the bag one at a time. Step 2: Record the weights on the five rectangles drawn in the chart below. Chart 1 Step 3: Find the sum of the five weights in the chart. Step 4: Divide the sum in Step 3 by five to find the average weight of the five-dog sample. Answer the following questions. Circle the correct answers where appropriate. 1. The 25 weights are a [population/sample]. 2. The five weights selected from the bag are a [population/sample]. 3. Since all 25 dog weights have an equal opportunity to be drawn, the sample is 4. Since each of the dog weights had an equal chance of being drawn, there are. members of the sample space. 5. In this experiment, there are possible outcomes. 6. The average weight of the five-dog sample recorded in the chart is pounds. 7. Based on the average weight of the five dogs, I predict that the average weight of the 25 dogs is pounds. For the next exercise, place the 25 rectangles with the dog weights in the bag again. Shake the bag to thoroughly mix the rectangles. Repeat the sampling procedure, this time drawing ten rectangles. Record the ten weights in Chart 2. Chart 2 Step 5: Find the sum of the ten weights in Chart 2, and divide by 10 to find the average weight of the ten-dog sample
