Do the data provide convincing evidence that Trey's school has a different proportion of walkers than claimed by the report? Use a = 0.01 Evidence PLAN: Identify the appropriate inference method and check conditions. Name of procedure: Check conditions: DO: If the conditions are met, perform the calculations. Mean: Picture: SD:
