Assume that the sample is a simple random sample obtained from a population with a normal distribution. Construct separate 90% confidenceinterval estimates of a using the two-line wait times and the single-line wait times. Do the results support the expectation that the single line has less variation? Do the wait times from both line configurations satisfy the requirements forconfidence interval estimates of a?Click the icon to view the data on wait times.Construct a 90% confidence interval estimate of σ using the two-line wait times☐ second(s) <<second(s)(Round to the nearest whole number as needed.)Question Viewer

Certainly! To compare the variation between the two line configurations, we need to examine the…

The following are auditor judgments and attributes sampling results for six populations. Assume large population sizes. 1 2 3 4 5 6 EPER (in percent) 2 0.5 1 0 2 5 TER (in percent) 6 4 20 3 8 10 ARO (in percent) 10 5 10 5 5 10 Actual sample size 100 100 20 100 60 60 Actual number of exceptions in the sample 2 3 1 1 1 5 For each population, did the auditor select a smaller sample size than is indicated by using the attributes sampling tables in Table 15-8(p. 519) for determining sample size? What are the implications of selecting either a larger or smaller sample size than those determined using the tables? Calculate the SER and CUER for each population. For which of the six populations should the sample results be considered unacceptable? What options are available to the auditor? Why is analysis of the exceptions necessary even when the populations are considered acceptable? For…
