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 perform 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)?
