ABC Investment company invests clients' money across 200 different investment portfolios, each of which has been structured and managed by a specialist portfolio manager. Mr. X, the Director of ABC Investment suspects that a significant difference exists between the returns on portfolios managed by male portfolio managers and those managed by female portfolio managers. Mr X decided to conduct an empirical study to determine whether the returns on portfolios differ significantly according to the gender on the portfolio manager. 120 portfolio managers were chosen for this study and they completed a questionnaire which included a demographic information sheet on gender, age, educational level and job tenure. The average annual returns of the portfolio managed by each of the 120 portfolio managers were objectively measured using data from the database of ABC Investment.
