Since the sample proportion (1344/2800) is used to calculate the confidence interval and it is based on a large enough sample size (n=2800), the confidence interval should contain the true population proportion with a high level of confidence. Therefore, it is unlikely that the 99% confidence interval will not contain the sample proportion.
