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.

How does this provision, which essentially turns $60 of variable costs into a fixed cost for you, discourage a supplier’s competition from stealing business?
Answer the following questions thoroughly. 1. Research the baseball players’ strike of 1980, which took place in two parts: spring training and later in the season. Analyze this choice by the players in terms of BATNAs. You should know that players are paid uniformly throughout the season when they are not on strike but not during spring training. Also, game attendance is highest late in the season. 2. Create the Value Net for your own business or a business with which you are familiar. Take special care in thinking about complementors; they are often overlooked. 3. A rule in a contract, generally one with a commodity supplier, is the take-or-pay provision. It is usually used with commodity suppliers that have high fixed costs. As an example, you agree to buy 100 units from a supplier at $80 per unit. If you buy less, you still have to pay $60 for each unit not bought. How does this provision, which essentially turns $60 of variable costs into a fixed cost for you, discourage a supplier’s competition from stealing business?
