b. To estimate or make inference about a population parameter, researchers may take one of the two approaches: using confidence interval or using the method of hypothesis testing. - Explain the difference between the two approaches. - Do you think they should lead to the same conclusion about the population parameter? - How do you increase the confidence that your interval contains the estimated parameter, that is, increase your precision, without having to increase your confidence level
