A pharmaceutical company is developing a new drug to treat a certain medical condition. The company has conducted a clinical trial to test the efficacy of the drug. The trial included 200 patients, half of whom were randomly assigned to receive the new drug and half of whom were randomly assigned to receive a placebo. At the end of the trial, 50% of the patients who received the new drug showed improvement, compared to only 30% of the patients who received the placebo. Test the hypothesis that the new drug is more effective than the placebo using a significance level of 0.01. Also, calculate the p-value and the 95% confidence interval for the difference in proportions between the two groups.
