The mean and standard deviation of a random sample of n measurements are equal to 33.7 and 3.3, respectively. a. Find a 95% confidence interval for p if n = 121. b. Find a 95% confidence interval for μ if n = 484. c. Find the widths of the confidence intervals found in parts a and b. What is the effect on the width of a confidence interval of quadrupling the sample size while holding the confidence coefficient fixed? a The 95% confidence interval for p if n = 121 is approximately ( (Round to three decimal places as needed.)
