Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p, the margin of error, and the confidence interval. Assume the results come from a random sample. A 99% confidence interval for p given that p = 0.42 and n = 475. Round your answer for the best point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places. Best point estimate - Margin of error = + The 99% confidence interval is to i Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 3 % significance level. Test Ho : p = 0.5 vs H. : p > 0.5 using the sample results p = 0.60 withn = 25 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic - p-value - i Conclusion: Ho
