A recent survey of academic major and starting salary of graduates showed thefollowing information:StandardMajorMeandeviationEnglish$38,100$3,600$5,870ComputerScience$57,6901) Calculate the coefficient of variation, and detormine which of the two majors varies more aroundthe mean salary? Show all your working answers.2) If you know that a computer science major who responded to the survay received a startingsalary of $64,000, find the z score of this solary What is your interpretation of this z-score value?
