Question
Activity 1: Proportion of undernourished children In a random sample of 500 children from Illinois, 143 were undernourished. Use these sample data to answer the following questions. A. Use the five-step hypothesis testing procedure outlined below to determine if there is evidence that the proportion of all children in Illinois who are undernourished is different from 0.5. Use Minitab. If assumptions are met, use the normal approximation method. You should not need to do any calculations by hand, other than checking assumptions. Remember to include all relevant Minitab output and identify your answers to each step. Activity 1_A: Step 1: Check assumptions and write hypotheses. Activity 1_A: Step 2: Calculate the test statistic. Activity 1_A: Step 3: Determine the p-value. Activity 1_A: Step 4: Decide to reject or fail to reject the null. Activity 1_A: Step 5: State a "real world" conclusion.
