In a random sample of

225

students at a university,

186

stated that they were nonsmokers. Based on this sample, compute a

95%

confidence interval for theproportion of all students at the university who are nonsmokers. Then find the lower limit and upper limit of the

95%

confidence interval.

Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult alist of formulas.)

Upper limit:
