Esther's aims to construct a confidence interval for the mean of a normal population with known standard deviation. List three factors that could help her in reducing the size of margin error. Then, she collects a random sample of size from a population and from the data collected she compute a 95% confidence interval for the mean of the population. Based on the same dataset, state one factor that could produce a new confidence interval with larger width (Hint: Larger margin of error)
