Question
IlI. Report a defensible results A technician is being trained to measure blood alcohol concentration with a method. He measured the table1. validated same sample five times and got the result in the following 1. Calculate the following listed in the table and give the function in exce l you used concentration (g/100 mL) measurement 0.085 0.094 0.090 0.081 5 0.087 answer results mean Standard deviation (sample) function in Excel student t (at 99.9% confidence level) confidence level (99.9%) 99.9% confidence interval range If the true value of the sample is 0.092±0.005 g/100 mL (at 99.9% confidence level), is the trainee's mean the same as 99.9% confidence level? Why? 2. 3. What is the relative error of trainee's measurement?Explanation / Answer
