5. Certified Reference Materials (CRM) are prepared in ISO17025 accredited laboratories and sold forthe purpose of device calibration. Under some standards the ISO17025 labs must measure their CRMproduct using two different assay methods that must agree with each other to within some specifiedamount. The Excel data file contains the assay results from two such methods.a. Perform the two-sample t test for Hoμ₁ =μ2 versus H₁ μ₁ μ2.10ppmb. Perform a two-sample equivalence test of Ho |Aμ| > 6 versus Ho|Aµ| < d using 6 =and show the equivalence test plot. In the Options submeu choose the (1 - 2α) confidenceinterval method.c. Explain how the two tests are different from each other. MethodPPM140714271416142914141417222222430419425417417434

The authors of the paper "Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement"† compared two different instruments for measuring a person's ability to breathe out air. (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen people participated in the study, and for each person air flow was measured once using the Wright meter and once using the mini-Wright meter.

The automated data collection system for a manufacturing process will record data for 25,000 parts per day. Assume that, when stable, a certain process will operate with a nonconformance rate of 37.6 NCPPM (nonconforming parts per million). If the nonconformance rate per day is to be monitored using a control chart, what type of chart would be used? Choose a P, U, or X-Bar/S Charts, and explain in a few words.
Mizutani and colleagues reported the development of a new method for the analysis of I-malate. As a part of their study, they analyzed a series of beverages using both their method and a standard spectrophotometric method based on a clinical kit to investigate the precision. A summary of their results is shown in Table 2. Determine whether there is a significant difference between the two methods at a 95% significant level.
