a.) 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. Answer all parts please, not just the confidence interval. A 95% confidence interval for p given that p-hat=0.75 and n=100. Round your answer for the point estimate to two decimal places, and your answers for the margin of...

- 9 of 13 ID: MST.HT.TP.01.0060 [1 point] A confidence interval is constructed for an unknown population proportion, p. A sample is collected, and the 95% confidence interval is calculated to be 0.43 + 0.05. Based on this information, it is most accurate to say that there is approximately 95% confidence in the assertion that: the population proportion is between 0.38 and 0.48 the sample proportion is between 0.38 and 0.48 the population proportion is 0.43 O the sample proportion...
