- Chemistryarrow_forwardA young researcher was evaluating a standard method for determining the methylmercury content in blue fin tuna using high performance liquid chromatography (HPLC). She determined the standard deviation (?)(s) for the method to be 0.440.44 ppb and assumed that ?s was a good approximation of ?σ . As a test, she used this method to evaluate the methylmercury content in a National Institutes of Standards and Technology (NIST) standard and determined the unknown amount to be within 0.210.21 ppb (?)(μ) of the known mean with 99% probability. How many replicate measurements of the NIST standard did the researcher perform?arrow_forwardGive all the answersarrow_forward

- i) To estimate the accuracy and precision of the method of determination of glucose in a blood sample, blood was spiked with a 88.2 ngml1 of glucose. The amount of glucose was determined in the spiked sample giving the following results in ngml1, 83.6, 69.0, 83.4 100.0 and 76.4. a)Find the accuracy of the quality control sample. b)Find the precision of the quality control samplearrow_forwardA group of students titrate a calcium carbonate standard solution repeatedly in five experimental trials. Based on the five trials, the group determines that the average concentration of the standard is 80.5 ppm with a standard deviation of 0.5 ppm. Using the equation for the Student's t confidence interval found in Appendix 1 of your lab manual and the t-value for a 95% confidence interval, calculate the confidence interval for which there is a 95% chance of finding the "true value" of the standard solution's concentration based on the data. Put your answer in the format # lower limit < "true value" < # upper limit.
