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

When a process tolerance is larger (has wider spread) than the product specification limits, the process will: Select one: a. Need to be controlled statistically b. Be under control c. Produce defects causing costly scrap and rework d. Produce few defects
A limousine company is concerned with increasing costs of maintaining their fleet of 150 cars. After testing, the company found that the emissions systems of 9out of the 20 cars they tested failed to meet pollution control guidelines. They had forecasted costs assuming that a total of 54cars would need updating to meet the latest guidelines. Is this strong evidence that more than 36% of the fleet might be out of compliance? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. What are the null and alternative hypotheses? What is the value of the test statistic? What is the P-value of the test statistic? What is your conclusion?

The U.S. Department of Health monitors fishing waters, to determine if the bacteria count has risen above a maximum safe level of 70. The following observations were obtained from 9 random samples of a stream: 69, 74, 75, 70, 72, 73, 71, 73, and 68. Can you say that the bacteria are above the safe level (alpha=0.05)? Calculate the appropriate test statistic. What is the critical value for the test? Would you issue a warning about the bacteria levels in the stream? Why?
A new screening test for thyroid cancer was administered to 1,000 adult volunteers at a large medical center complex in Europe. The results showed that 152 out of 160 diagnosed cases of thyroid cancer were correctly identified by the screening test. Also, of the 840 individuals without thyroid cancer, the screening test correctly identified 714. Base on this information, calculate the test's: 1. Sensitivity 2. Specificity 3. Positive predictive value 4. Negative Predictive Value 5. Accuracy 6. Prevalence rate. Please help with 4,5,6. I have attached 1,2,3.
According to the Pew research center 65% of US adults believe that the government should play a larger role in addressing climate change. A random sample (SRS) of 80 US adults found that 56 US adults believe that the government should play a larger role in addressing climate change. Does this indicate that population proportion of US adults who believe that the government should play a larger role in addressing climate change is MORE THAN 65%? Given: a= 0.05 level 1.
