Exam 15: A: Advanced Methods for Project Scheduling

Which of the following categories of causes would be most appropriate for a Marriott (an international hotel chain)or McDonalds (an international fast food chain)or the local hair stylist?

Which of the following conclusions does the p data shown below support? P = .10 UCL = 0.2022 LCL = 0.-0154

Under what conditions would we be required to recalculate the parameters for an X-bar-R chart?

Which of the following types of control charts would be most appropriate if the data that we are dealing with is binary in nature (good/bad,pass/fail,accept/reject)?

Forty samples of 100 are taken,with the total number of defective units being 150.What is the upper control limit of the three sigma (z = 3)p-chart?

To determine whether two variables are related to each other you would use:

Sample means and ranges were obtained for five samples of 10 units per sample from a production process.Assume the process was considered to be in control during the period these samples were collected.The results are as follows: What is the central line of the X chart for this process

Effective quality management requires:

A packaging plant is running a filling process where packages are filled with 24 oz.+/- 0.08 oz.A capability study reveals that the process mean is 24 oz.with a standard deviation of 0.02 oz.What is the capability of the packaging line?

The specifications for the diameter of a molded part are 10 mm ± 0.5 mm.The actual average and standard deviation from 250 parts sampled is 10.1 mm and 0.1 mm,respectively.What is the process capability as measured by C_p?

Sample means and ranges were obtained for five samples of 10 units per sample from a production process.Assume the process was considered to be in control during the period these samples were collected.The results are as follows: LCL for the three sigma X chart for the process is approximately (for a sample size of 10,A2 = 0.31):

You are given the following data for taillight assemblies: Management has decided to carry out a Pareto analysis focusing on problem areas.Which of the following conclusions does the Pareto analysis support?

Which of the following tools is most appropriate when we are interested in determining if a process that was generating attribute-type data (pass/fail,good/bad)was under control?

We are experiencing a problem where the output of a process keeps shifting over time.If we were to use a histogram to collect and display the resulting data,what type of shape would it most likely display?

Which of the following conclusions does the p data shown below support? P = .10 UCL = 0.2022 LCL = 0.-0154

Which of the following quality improvement tools is not a particularly good brainstorming tool?

Measuring quality in brief customer interactions is particularly difficult,as each customer's interaction with a company employee has the potential to be personal and unique.Some service firms have attempted to measure the effectiveness of these transient customer interactions using which of the following scales?

A firm has an existing process that it would like to use for producing a part it will sell to an industrial customer.The customer requires that defective (out of specification)parts be kept to 3,000 parts per million (three-tenths of 1 percent)or less.A process capability study done on the process revealed that it has a process capability index (C_pk)of 1.00 for this part.What should the firm conclude from the study?

You have been given the following sample information that has been drawn from the last sample taken: Mean of the sample: 13.67 Lower control limit for the range: 0 Upper control limit for the range: 10.6 Observations: 13,12,8,10,11,16,17,8,17,18,20,14 Which of the following conclusions does this data support?

The two types of data involved in quality control are:
