Answer:

Standard error (S.E) = 0.048 ≅ 0.05

Step-by-step explanation:

<u>Explanation</u>:-

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
