Confidence interval for a population proportion.
In a random sample of 400 students at a university, 332 stated that they were nonsmokers. Based on this sample, compute a 95% confidence interval for the proportion of all students at the university who are nonsmokers. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places
(a)What is the lower limit of the confidence interval?
(b) What is the upper limit of the confidence interval?
