A trainee in a medical lab will be released to work on her own when her results agree with those of an experienced worker at the 95% confidence level. Results for a blood urea nitrogen analysis are shown below. Subscripted numbers indicate the first insignificant figure in each value. Report your tcalculated to the same number of decimal places as your ttable (3 decimal places, please).
Table of student\'s t probablities
ttable, 95% = ?? ... tcalculated, 95% = 2.12
| Trainee | mean = 14.57 mg/dL | standard deviation = 0.53 mg/dL | n = 6 samples |
| Experienced Worker | mean = 13.95 mg/dL | standard deviation = 0.42 mg/dL | n = 5 samples |
