Chapter 1, Problem 1.22P

The sale of motor fuel is an essential business in the global economy. Federal (U.S.) law requires the quantity of fuel delivered at a retail establishment to be accurate to within 0.5%. (i) Determine the maximum allowable error in the delivery of 25 gallons (or use 95 L). (b) Provide an estimate of the potential costs to a consumer at the maximum allowable error over 150,000 miles (240,000 km) based on an average fuel mileage of 30.2 mpg (7.8L/100km). (c) As a knowledgeable consumer, cite one or two ways for you to identify an inaccurate pump.

compute the 95 confidence intervals for the inventory of a series of 12 replication of the simulation of a system, where the VERAGE INVENtory is 1000 units and sample standard deviation is 38
The following data provide the time in months from hire to promotion to manager for a random sample of 25 software engineers from all software engineers employed by a large telecommunications firm. 5 7 229 453 12 14 18 14 14 483 22 21 25 23 24 34 37 34 49 64 47 67 69 192 125 Calculate the mean, variance, and standard deviation for this sample.
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.
