Question

A dean of a business school wanted to know whether the graduates of her school used the statistic skills that they learn in university during their first year of employment after graduation. As of today there are 34,050 graduates in total from the business school. The Dean is committed to allocate more funding to the development of the school’s statistics course if at least 17% of its graduates use statistics skills during their first year of employment. She surveyed 500 graduates. 105 graduates responded that they actually find the statistic skills they learnt in university useful and applicable in their first year of employment. Estimate with 95% confidence the proportion of all of the business school graduates who use their statistic skills during their first year of employment.
