In 2010, the United Nations claimed that there was a higher rate of illiteracy in men than in women from the country of Qatar. A humanitarian organization went to Qatar to conduct a random sample. The results revealed that 45 out of 234 men and 42 out of 251 women were classified as illiterate on the same measurement test. Do these results indicate that the United Nations' findings were correct?
1. Test an appropriate hypothesis and state your conclusion.
2. Find a 95% confidence interval for the difference in the proportions of illiteracy in men and women from Qatar. Interpret your interval.

Of 540 Packers fans surveyed, 215 fans were satisfied with the team's draft picks since 2010. Let p represent the proportion of fans that are satisfied with the Packers draft picks.
Create a 99% confidence interval for satisfied Packer fans and give its lower bound as your answer.
Nationwide, football fans since 2010 on average have been satisfied with their team's draft performance 45% of the time. Matt LaFleur wants to know if Packers fans really are less satisfied than the league average. Using the 540 Packers fans sampled in the previous question, LaFleur tests the hypothesis H0 : p = 0.45, Ha : p < 0.45.
