If both left and right end foundations on the banks are stabilized so that their settlements are negligible, specify the maximum allowable relative settlement of the center pier for the design engineer so that any maximum relative design settlement would exceed this value with a probability of only 0.0001.
A proposed bridge is supported at two ends and one a center pier. Although the design allows for relative settlements of the foundations, the engineer needs to keep these settlements within limits. Settlements caused by the sum of numerous dead loads and impacts of moving vehicles are assumed to be normally distributed, with the variability arising from the effects on the soil by the foundation. By correlating with test results from similar structures and soil conditions, estimates of the settlements were made as follows Bridge Mean Settlement (in) Std.Dev. (in) Left end 3 1 Center pier 5 1.5 Right end 3 1 If both left and right end foundations on the banks are stabilized so that their settlements are negligible, specify the maximum allowable relative settlement of the center pier for the design engineer so that any maximum relative design settlement would exceed this value with a probability of only 0.0001.

- AuCement produces many types of cements products at its factory in Sydney and sells them in Sydney, Brisbane, Canberra, and Melbourne. Six month ago, the company established a new cement facility in its factory to load a new 20Kg packaged cement. The company sells this new product in a competitive price and has boosted its sales with this option. In every contract the price of the product is paid based on its delivery time and customer satisfaction. To investigate more about the sales, they surveyed the customers who have purchased this kind of cement and a sample of 50 receipts was selected from the previous sales. For better comparison, they scaled the delivery time with dividing the hours spent for delivering the product by the travelled kilometres. AuCement file contains data showing the customer’s location, the payment type, the delivery time, the amount of customer satisfaction, and the price of sales paid for every tonne of this product by each of the 50 customers.
AuCement would like to use the sample data to determine whether customers who receive their package earlier and are more satisfied about the quality also pays higher prices. The company would also like to investigate the effect that the customer location and the payment type have on sales.
Managerial Report
Use the methods of descriptive statistics to learn about the customers who purchase in higher prices. Include the following in your report:
1) Graphical and numerical summaries for the length of delivery time, the customer satisfaction factor, and the average amount gained per sale. Discuss what you learn about AuCement’s new product sales based on this data.
2) Summarise the frequency, the average sale price, average delivery time, and average customer satisfaction for each city. Discuss the observations you can make about AuCement’s business based on the destination city of the sales?
3) Develop a scatter diagram, and compute the sample correlation coefficient to explore the relationship between the delivery time and the selling price. Use the horizontal axis for the delivery time of the new product. Discuss your findings.
4) Develop a scatter diagram, and compute the sample correlation coefficient to explore the relationship between the delivery time and the customer satisfaction. Use the horizontal axis for the delivery time of the new product. Discuss your findings.
5) Develop a scatter diagram, and compute the sample correlation coefficient to explore the relationship between the customer satisfaction and the sale price of new product. Use the horizontal axis to represent the customer satisfaction. Discuss your findings.
- Ambulance Victoria has an official Response Time (RT) targets: Respond to incidents within 15 minutes for 85% of incidents state-wide. Response times are an important measure of the service they provide. The response times are measured from the receipt of the triple zero (000) call until paramedics arrive on scene. Response times are influenced by many factors including traffic, distance required to travel, availability of ambulances and demand for the services. They designate those patients that require urgent paramedic and hospital care as “Code 1,” and these patients receive a “lights and sirens” response. The AmbulanceVictoria file provides information about their Code 1 response time performance by Local Government Area (LGA) in the 3rd quarter of the financial year 2015-2016.
Managerial Report
Use the data-visualization methods presented in this chapter to explore these data and discover relationships between the variables. Include the following in your report:
1) Create a scatter chart to examine the relationship between the average response time and the total number of incidents. Include a trend line for this scatter chart. What does the scatter chart indicate about the average response time over the total number of incidents for these Victoria’s LGAs?
2) Create a scatter chart to examine the relationship between the percentage of less than 15 minutes response times and the average response time. What does this scatter chart indicate about the relationship between the percentage of less than 15 minutes response times and the average response time?
3) Create a frequency distribution, percent frequency distribution, and histogram for the number of incidents. Use bin size of 100 incidents. Interpret the results. Do any data points appear to be outliers in this distribution?
4) Create a PivotTable for these data. Use the PivotTable to generate a cross tabulation for LGA categories and rating. Determine which combinations of LGA categories and rating are most represented in the Ambulance Victoria data. Now filter the data to consider only area with average response time more than 15 minutes (900 seconds). What combinations of LGA categories and rating are most represented? What does this indicate about how the ranking of the LGAs may be defined for the other quarters of the year?
5) Use the PivotTable to display the average incidents happened in each combination of category-rating pair of areas in the data set. Interpret the results.

ElectriGov is a government agency whose mission is to supply electric power to various locations in the United States.
Case One: ElectriGov
ElectriGov is a government agency whose mission is to supply electric power to various locations in the United States. To accomplish this task, the organization has three line crews of five to ten men whose job it is to install high-voltage power lines. Each crew is highly cohesive, led by a foreman. Moreover, crew members have worked together for many years and have an established pattern for doing their work and solving problems. The work is hard, dirty, and dangerous. Almost all of the men have had a friend who has been seriously injured or killed while on the job.
The crews typically work independently, but when there are large projects to complete, they must work together. This can create serious conflicts, since the crews often don’t agree with each other’s approaches to organizing and managing a particular job, and none of the three foremen wants to be subservient to the others. Thus when line crews do large projects together, they tend to compete with one another rather than cooperate. On one project, the conflict became so nasty that one crew failed to inform another crew that the wires were hot at a certain section of the project. The serious safety breach was reported to senior management, who immediately launched an investigation. We, as consultants, were initially asked to serve as part of the team investigating the causes of the safety violations.
After the initial investigation, we were asked by ElectriGov’s senior management to “clean up the conflicts” between the crews. The approach we used to help the crews reduce their conflicts was a variation on design A. All three crews were brought together in one room, and the need for an interteam development program was discussed. Each crew was asked to commit to solving the conflicts between themselves and the other crews and to agree to give the program a chance. Once we had their agreement, each crew was then asked to meet separately to list their perceptions of the other crews and the specific problems that they had in working with the others. After meeting separately, the teams came back together and each reported its perceptions of the other crews.
In our consulting role, we facilitated the discussion, making sure that each crew’s perceptions were made clear and that each crew described the problematic behaviors of the other crews in concrete, specific terms. As a ground rule, crews were asked to be descriptive and to avoid using emotionally laden language when critiquing the other crews. After each crew presented its perceptions, the other crews could ask questions to clarify points, but crews were not allowed to debate the validity of the other crews’ perceptions.
After each crew aired its views, the crews, together in an open session, were then asked to come up with recommendations to improve the relationships. Their suggestions were listed on large poster boards in the room. The crews discussed how they might do more advanced planning on the larger projects to determine who would do what and who would be in charge of the project. They also considered rotating crew members to improve relationships between crews. Most important, the crews agreed on a common goal; avoiding accidents at all cost.
At the end of this interteam-building session, each crew made a public commitment to change its behavior and implement recommendations. As a result of this intervention, the crews now have a new approach to working with each other on large projects that minimizes the conflicts that they had in the past.
