If a sample of 100 people contains 15 left-handed: (a) Compute a 95% confidence interval for the proportion of left-handers in the population. (b) If we were to take a larger sample the next time we do this experiment, would we expect the confidence interval to be wider or narrower than the one in part (a)? Why? (c) If we compute a confidence interval with a higher (say 98%) confidence level for the sample in part (a), would the new confidence interval be wider or narrower than the confidence interval computed in part a)?
