An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 200 engines and the mean pressure was 4.5 pounds/square inch (psi). Assume the population standard deviation is 0.7. If the valve was designed to produce a mean pressure of 4.4 psi, is there sufficient evidence at the 0.01 level that the valve does not perform to the specifications? Step 4 of 6: Find the P-value of the test statistic. Round your answer to four decimal places.

One kg of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from a saturated liquid at 50 bar until is a saturated vapor. The vapor then expands adiabatically to a pressure of 5 bar and a quality of 0.8291. a) Sketch the cycle on P-v and T-s diagram. b) Evaluate the heat transfer and wor for the above processes (isothermal expansion and adiabatic expansion) c) Evaluate the thermal efficiency.

Consider the two air conditioning systems detailed below. Use AW analysis to determine the sensitivity of the economic decision to MARR values of 4%,6%, and 8%. Work this problem (a) by hand and (b) by spreadsheet.
Suppose that Motorola uses the normal distribution to determine the probability of defects and the number of defects in a particular production process. Assume that the production process manufactures items with a mean weight of 10 ounces. Calculate the probability of a defect and the suspected number of defects for a 1,000-unit production run in the following situations. a. The process standard deviation is 0.15, and the process control is set at plus or minus one standard deviation. Units with weights less than 9.85 or greater than 10.15 ounces will be classified as defects. b. Through process design improvements, the process standard deviation can be reduced to 0.05. Assume that the process control remains the same, with weights less than 9.85 or greater than 10.15 ounces being classified as defects. c. What is the advantage of reducing process variation, thereby causing process control limits to be at a greater number of standard deviations from the mean?
The firm, Bolta Ltd, manufactures high precision specialized nuts and bolts that are customized for the needs of specific applications. It has received an enquiry from the Spaceways Company to supply high precision bolts that are needed for their new spacecraft designed to take passengers for a flight over the earth to the limit of earth’s atmosphere of 100 kms and back, hopefully alive and safe. Special bolts are needed that will not be affected by the temperature difference as the spacecraft goes up to the outer atmosphere and on its decent back to the ground. It is expected that the requirements will be about 3 million units in year 1, which will increase by 15% for 2 years up to year 3, and then decrease by 15% for another 2 years. Current plans foresee demand for these specialized nuts for only 5 years. The price per bolt in year 1 is expected to be $ 50 which will increase by 8% each year to account for inflation. Variable cost is 50% of sales. Fixed cost is $ 6 million in year 1…
1. A variety of routine maintenance checks are made on commercial airplanes prior to each takeoff. A particular maintenance check of an airplane's landing gear requires an average of 15 minutes of a maintenance engineer's time. In fact, the exact time required is normally distributed with a mean of 15 minutes and a standard deviation of 3 minutes. As part of a larger simulation model designed to determine the total on-ground maintenance time for an airplane, we will need to simulate the actual time required to perform this maintenance check on the airplane's landing gear. Using random numbers of 0.1562, 0.9821, 0.3409, 0.5594, and 0.7758, compute the time required for each of five simulated maintenance checks of the airplane's landing gear.
Two masses are connected to a string and hung on a pulley to make an atwood machine. The masses are different values such as M > m. The setup is shown. Assume the string is massless and the pulley is ideal. When the masses are gently released, there is a resulting acceleration. Which of the following equations will calculate the mass of m in the system if the big mass and acceleration are known? A) m = 2M(a/g). B) = m 2M(g/a). C) m = M(g- a/g+a). D) m = M(g+a/g -a).
In a manufacturing process the assembly line speed (feet per minute) was thought to affect the number of defective parts found during the inspection process. To test this theory, managers devised a situation in which the same batch of parts was inspected visually at a variety of line speeds. They collected the following data: Develop a scatter chart with line speed as the independent variable. What does the scatter chart indicate about the relationship between line speed and the number of defective parts found? Use the data to develop an estimated regression equation that could be used to predict the number of defective parts found, given the line speed. What is the estimated regression model? Test whether each of the regression parameters β0 and β1 is equal to zero at a 0.01 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable? How much of the variation in the number of defective parts found for the sample data does the model you estimated in part (b) explain?

An existing robot is used in a commercial material laboratory to handle ceramic samples in the hightemperature environment that is part of several test procedures. Due to changing customer needs, the robot will not meet future service requirements unless it is upgraded at a cost of $2,000. Because of this situation, a new advanced technology robot has been selected for potential replacement of the existing robot. The accompanying estimates have been developed from information provided by some current users of the new robot and data obtained from the manufacturer. The firm’s before-tax MARR is 25% per year. Based on this information,should the existing robot be replaced? Assume that a robot will be needed for an indefinite period.
John Cartwright gathered data on the relative costs of a solar water heater system. The data are based on statistics which they have broken down into 4 categories. Low sunlight days will heat 2.0 gpm of water to the desired temperature of 120F for 4 hours/day. Medium sunlight will heat 2.5 gpm of water to the desired temperature for 4 hours/day. Strong sunlight will heat 3.0 gpm of water to the desired temperature for 4 hours. Very strong sunlight will heat 3.3 gpm of water to the desired temperature. - If they can offset heating of water with an electric heater, they will save $2.0 per gallon. If the probably of sun of each of the 365 day year is: Low sunlight - 30%, Medium sunlight - 40%. Strong Sunlight- 20%, Very Strong - 10% for Ohio.
