This exercise is a "what-if analysis" designed to determine what happens to the interval estimates when elements of the statistical inference change. You may need to use the appropriate appendix table to answer this question. (a) in a random sample of 240 observations, we found the proportion of successes to be 43%. Estimate with 95% confidence the population proportion of successes. (Round your answers to four decimal places) lower bound upper bound O (b) Repeat part (a) with n=600. (Round your answers to four decimal places) lower bound upper bound (c) Repeat part (a) with n=1,000. (Round your answers to four decimal places) lower bound upper bound (d) Describe the effect on the confidence interval estimate of increasing the sample size.. When the sample size increases, the confidence interval --Select-- 4
