A random sample of 450 Cincinnati residents was asked which chili they prefer: Skyline chili or Goldstar chili. Suppose that 45% of those surveyed said they prefer Skyline chili. When a 95% confidence interval was constructed based on this data, the interval ended up being from 40.4% to 49.6%. Based on this information, which of the following statements is correct?1. The margin of error would be larger if the sample size were bigger than n = 450.2. The value of 45% is a statistic.3. The value of 45% is a parameter.4. It would be impossible to know what the margin of error is without more information.5. If we were to select many more random samples of size n = 450 from the population of Cincinnati residents, 95% of the resulting confidence intervals would be from 40.4% to 49.6%.

Given that Sample proportion p^=45% 95% confidence interval is 40.4% to 49.6%.
