Problem 4 A study of MBA graduates by Universum for The American Graduate Survey 2017 revealed that MBA graduates have several expectations from prospective employers beyond their base pay. In particular, according to the study, 46% expect a performance related bonus, 46% expect stock options, 42% expect a signing bonus, 28% expect profit sharing, 27% expect extra vacation/personal days, 25% expect tuition reimbursement, 24% expect health benefits, and 19% expect guaranteed annual bonuses. Suppose a study is conducted in an ensuing year to see if these expectations have changed. If 125 MBA graduates are randomly selected and if 66 expect stock options, is this enough evidence to declare that significantly higher proportions of MBA's expect stock options? Let a =.05 (4 marks)
