Given  sample size 'n'=76

Given the dean who randomly selects 76 students and finds that 58 out of 76 are receiving financial aid.

Sample proportion

                         p = \frac{x}{n} = \frac{58}{76} = 0.7631

The standard error is determined by

                     S.E = \sqrt{\frac{p(1-p)}{n} }

                     S.E = \sqrt{\frac{0.763(0.2369}{76} }

  Standard error is 0.048  ≅ 0.05
