A researcher believes nurses are absent from work more frequently when they score higher on a test of "psychological burnout". These data are collected: Burnout (X) Absences (Y) 2 4 1 7 2 6 3 9 4 6 4...

Using the data, answer the following:

• 
  
  
  
  • Compute the correlation coefficient
  
  
  • What are H₀ and H_a? (Note: this is a one-tailed test)
  
  
  • With α = 0.05, report
    r
    _crit (Note: this is a one-tailed test)
  
  
  • What do you conclude about the strength of this relationship?
  
  
  • Calculate the proportion of variance accounted for
