- In a manufacturing plant a work center is a specific production facility that consists of one or more people and or machines and is treated as one unit for the purposes of capacity requirements for planning and job scheduling. If jobs arrive at a work center faster than they depart the work center impedes overall productions and is referred to as a bottleneck. The data below was collected by a plant manager for use in investigating a potential bottleneck work center. Construct a histogram for each data set. Do your histograms suggest that the work center may be a bottleneck? Explain.

- Errors in medical prescriptions occur and a study1 examined whether electronic prescribing may help reduce errors. Two groups of doctors used written prescriptions and had similar error rates before the study. One group switched to e-prescriptions while the other continued to use written prescriptions, and error rates were measured one year later. The results are given in Table 1. Error No Error Total Electronic 254 3594 3848 Written 1478 2370 3848 Table 1 Are prescription error rates different? Find a 99% confidence interval for the difference in the two proportions, pw-pe, where pw is the proportion of errors using written prescriptions and pe is the proportion of errors using e-prescriptions.Round your answers to three decimal places.Food deserts have become a particularly hot topic in the public health community as an explanation for a variety of negative health outcomes in disadvantaged areas.
