A trainee in a medical lab will be released to work on her own results agree with those of an experienced worker at the 95% confidence level. Results for a blood urea nitrogen analysis are shown below.
Trainee: X= 14.5 mg/dL s= 0.53 mg/dL n= 6 sampels
Experienced: X= 13.9 mg/dL s= 0.41 mg/dL n= 5 samples
Should the trainee be released to work alone?
