An organic farmer wants to encourage people in his community to start composting more as he thinks it is good for the environment. He thinks that creating a YouTube channel with videos demonstrating how easy it is to compost might be an effective way to increase the proportion of people in his area that create their own compost piles. He creates a YouTube channel and shares the link with the people who are on his neighborhood listserv. Use this information to answer the following questions.

1. What are the farmer's null and alternative hypotheses? Is the farmer's alternative hypothesis one-tailed or two-tailed? Explain.
2. The farmer conducts a hypothesis test and finds a p-value of 0.049. Should he reject the null hypothesis? Explain.
3. The farmer also wants to see if his YouTube videos will help increase the proportion of people between the ages of 18 to 25 who compost. He conducts a hypothesis test and finds a p-value of 0.004. Is it reasonable to conclude that his YouTube channel increased the number of 21-year-olds who compost? Explain.
