I have been having trouble understanding the answers for this prompt.

1. Suppose that Michigan lawmakers survey 500 randomly selected registered voters to see if they favor an extension of the fall duck hunting season. The lawmakers believe that the population proportion in favor of extending the duck hunting season is 45% (based on historical data and previous votes).
2. Check normality condition.
3. Assuming that the population proportion of those who favor extending the duck hunting season is 45%, find the probability that more than 49% of the sampled voters favor the extension of the fall duck season.
4. Assuming that the population proportion of those who favor extending the duck hunting season is 45%, find the probability that between 40% and 50% of the sampled voters favor the extension of the fall duck season.
