FringeTech is an information technology / electrical engineering company that employs thousands of people Australia wide. Recently management decided to ask employees to carry out a series of three tests based around firm procedures, general knowledge and a general intelligence test. All employees were then awarded a score out of 225.

Question 7) All companies are rightly concerned about the income disparity between Males and Females and FringeTech is no different. Is there any evidence in the data that Males are earning more than Females on average?
