The manager of the main laboratory facility at Center is interested in being able to predict the overhead costs each month for the lab. The manager believes that total overhead varies with the number of lab tests performed but that some costs remain the same each month regardless of the number of lab tests performed. The lab manager collected the following data for the first seven months of the year. Month Number of Lab test performed Test Laboratory overhead cost
January 2,800 $21,500
February 2,600 $22,700
March 3,100 $27,900
April 3,550 $31,400
May 3,700 $28,500
June 1,200 $19,500
July 1,400 $14,500
Requirements

2. Does the data appear to contain any outliers? Explain.
3. How strong of a relationship is there between the number of lab tests performed and laboratory overheadcosts?
