Question
i collect a random sample of size n from a population anf from the data collected compute a 95% confidence interval for the mean oc the population. Which of the following would produce a new confidence interval with smaller width (narrower interval) based on these same data? A) Use a larger condice level B) Use a smaller confidence level C) Use the same confidence level, but compute the interval n times. Approximately 5% of these intervals will be larger D) Nothing can guarantee absolutely thatvyou will get a smaller interval. one can only say the chance of obtaining a smaller interval in 0.05 i collect a random sample of size n from a population anf from the data collected compute a 95% confidence interval for the mean oc the population.

Option - B) Use a smaller confidence level.
Because as the confidence level decreases, the margin of error also decreases and the confidence interval becomes narrower.
