Two quality control technicians measured the surface finish of a metal part. Measurements are in the following table. Assume that the data are normally distributed. (a) State and test the hypothesis that the mean surface finish measurements made by the two technicians are equal at alpha = 0.05 assuming equal variances. (b) State and test the hypothesis that the variances are equal at alpha = 0.05 to verify the assumption of equal variances. Explains the steps to complete this using minitab.

Two different technicians (Tech A and Tech B) each measured the cardiac output for a sample of 26 patients using Doppler Echocardiography. The supervisor would like to use this paired data to assess inter-rater reliability by testing if the population mean difference in cardiac output is 0 (no difference on average) versus the alternative that there is a difference. The hypotheses to be tested are: H0: μd = 0versus Ha: μd ≠ 0, using a 10% significance level. A- The sample...

3.32. Quality Control. An automatic machine in a small factory produces metal parts. Most of the time (90% according to long-term records), it produces 95% good parts, while the remaining parts have to be scrapped. Other times, the machine slips into a less productive mode and only produces 70% good parts. The foreman observes the quality of parts that are produced by the machine and wants to stop and adjust the machine when she believes that the machine is not...
