To investigate the relationship between the number of unauthorized days that employees are absent per year and the distance (miles) between home and work for the employees, a sample was chosen and the data collected is in the Absent data file.

 a.Develop a scatter chart. Does a linear relationship appear reasonable? Explain.

 b.Use the data to determine the estimated linear regression equation that would predict the number of days absent given the distance to work. What is this estimated linear regression equation? 

c.Is the regression relationship significant? What is the conclusion at the 0.05 level of significance? 

d.What is the regression parameter β1? What does it mean in this problem? 

e.What would you predict the number of days absent would be for an employee living 15 miles from work?
