A flexible pavement has a 4-inch sand-mix asphalt wearing surface, 10-inch soil cement base, and a 10- inch crushed stone subbase. It is designed to withstand 400 20-kip single-axle loads and 900 35-kip tandem-axle loads per day. The subgrade CBR is 8, the overall standard deviation is 0.45, the initial PSI is 4.2, and the final PSI is 2.5. What is the probability that this pavement will have a PSI above 2.5 after 25 years? (Drainage coefficients are 1.0.) Use the editor to format your answer

Pressure distribution measurements are made on a two-dimensional wing model placed in a wind tunnel. The difference between the static pressure sockets on the surface and the static pressure of the free stream is measured. 30 data is taken at each measurement point. The average of the values measured from one of the sockets near the trailing edge was calculated as 2.30 Pa, and the standard deviation was calculated as 2.65 Pa. After applying the Chauvenet criterion to these measurement values, it was decided to eliminate 3 measurements and the new mean value was found to be 2.18 Pa and the standard deviation was 2.42. It was verified that the unexcluded data fit the normal distribution curve. Data above how many Pa and below how many Pa were eliminated? Estimate how many data have negative value (?<0) after elimination.
Some engineering components have a mean length of 20 mm and a standard deviation of 0.25mm. Assume that the data on the lengths of the components is normally distributed. In a batch of 50 components, determine the number of components likely to:i) Have a length of less than 19.95mmii) Be between 19.95mm and 20.15 mmiii) Be longer than 20.54 mm
Mr. C studies the strength of the material used for a baseball bat, he knows that the strength is approximately normally distributed with a standard deviation of 175 psi. A random sample 30 specimens has a mean strength of 2,750 psi. a) What is the z-value when the mean strength is tested to be 3,000 psi, b) What will be the decision for the hypothesis testing with a=0.05 c) What is the minimum mean tensile strength needed from 30 samples, for the claim of 3,000 psi to be failed to rejected.
The shear modulus, G, of an alloy can be determined by measuring the angular twist, θ,resulting from a torque applied to a cylindrical rod made from the alloy. For a rod of radius Rand a torque applied at a length L from a fixed end, the modulus is found by G=2LT/pR4θ.Examine the effect of the relative uncertainty of each measured variable on the shearmodulus. If during test planning all of the uncertainties are estimated to be 1%, what is theuncertainty in G?

Two soft drink machines dispense liquids of 10 ounces, on the average. The question is whether the two machines are equally consistent in the dispensing of the liquid. To answer this question, a sample of size 10 was obtained from each machine and the sample standard deviations were computed to be s1 = 1.87 ounces and s2 = 1.25 ounces. Perform the appropriate test of hypothesis using α = 0.05
In a yogurt filling line, the containers are filled with yogurt. The producer uses a scale with anaccuracy of 1,8 percent of its range of 9 kg to measure the mass of each container in order to calculate theuncertainty in mass of the containers. 19 containers are selected at random and measured. The averagemass is 2 kg, and the standard deviation of the measurements is calculated to be 0,89 kg. Calculate the total uncertainty of the average mass of the containers at a 95 % confidence level.
A manufacturer claims that the average tensile strength of thread A exceeds the average tensile strength of thread B by at least 12 kilograms. To test this claim, 50 pieces of each type of thread were tested under similar conditions. Type A thread had an average tensile strength of 86.7 kilograms with a standard deviation of 6.28 kilograms, while type B thread had an average tensile strength of 77.8 kilograms with a standard deviation of 5.61 kilograms. Test the manufacturer’s claim using a 0.05 level of significance. 1. Determine the Z calculated in two decimal places. 2. Determine the Z table in two decimal places. 3. Is the manufacturing claim statistically valid? yes or no
