Question

1. Suppose that 28% of all Americans have experienced times when they haven’t been able to afford sufficient food. Separately, you sample 801 Americans who are financially less well-off than average Americans and find that 38% reported that there had been times in the last year when they had not been able to afford sufficient food. Does this indicate that the problem is more severe among those American who are less well-off?

1. Test an appropriate hypothesis and state your conclusion. Make sure to check any necessary conditions and to state a conclusion in the context of the problem. Was your test one-tail upper tail, one-tail lower tail, or two-tail? Explain why you chose that kind of test in this situation.      
2. Find and explain what your P-value means in this context.
