APPLIED STATISTICS Given that, the 99% difference of the population means for the carbon content by two types of steel is between 0.0035 parts per million more by Steel Y to 0.0085 parts per million more by Steel X, compared to each other, respectively. (i) Calculate the margin of error. (ii) State the condition of sample size to get better estimation of the parameter used in the study.
A factory produces furniture as the main product. One of the major components of the furniture product is a steel bar with the specification of the length at 1,250 mm with +/- 10% tolerance. Based on historical records, the average demand for steel bars is 1,000 units per month. The factory receives two quotation prices from two independent suppliers along with the quality control records from their production process of the steel bars as below: (refer to table image) Anticipating that a portion of the steel bars delivered will fall outside the specification limits, the factory is prepared to cut steel bars that are too long, while those that are too short will have to be discarded. Based on the above information, answer the following questions: a. Provide your assessment on the capabilities (based on their capabilities index) of the two suppliers as well as their estimated percentage of defective products against the factory’s specification of the steel bars. b. Which of the two…

The Deepwater Horizon oil spill in the Gulf of Mexico on April 20, 2010 was "an environmental disaster of unprecedented proportions" and was a "devastating blow to the resource-dependent economy of the region" [1]. According to the Washington Post, it is estimated that 9857 9857 cubic meters of oil per day spilled into the Gulf of Mexico on August 2, 2010 Assume that an average of 9857 m^3/day of oil spilled into the Gulf of Mexico everyday and that it formed a hemispherical dome of radius r on the ocean floor. D) find the rate of change of the radius with respect to time when the volume of the oil spill is 50,000m^3. E) Since only the oil that is in contact with seawater can mix with seawater, it is important to know how much of the surface area of the oil spill is in contact with seawater. Find the rate of change of the hemisphere's surface area with respect to time when the volume of the oil spill is 50,000 m3. Include units in your answer. You should assume that only the top…
