Please answer this question clearly
The campaign manager for a political candidate claims that 55% of registered voters favor the candidate over her strongest opponent. Assuming that this claim is true, what is the probability that in a simple random sample of 300 voters, at least 60% would favor the candidate over her strongest opponent?
- What is the point estimate of the population?
- For this situation suppose that only 49% of the registered voters in the sample favor the candidate over her strongest opponent. Given this result:
- If the campaign manager's claim is correct, what is the probability that the sample proportion would be no more than 0.49 for a sample of this size
- Based on your answer to part (a), speculate on which type of error is made by the campaign manager's claim?
