During an engine test on the ground, a propeller thrust T = 4000 N is generated on the 1500 kg airplane with mass center at G. The main wheels at B are locked and do not skid; the small tail wheel a
It is thought that a new process for producing a certain chemical may be cheaper than the currently used process. Each process was run 6 times, and the cost of producing 100-L of the chemical was de
To determine the effect of fuel grade in fuel efficiency, 80 new cars of the same make with identical engines, were each driven for 1000 miles. Forty of the cars ran on regular fuel, and the other f
Measurements of groundwater concentrations of silica (SiO2) in mg/L, were made at a sample of 12 wells in Birmingham. The sample mean concentration was 61.3 and the standard deviation was 5.2.
Stack gas samples were collected from a sample of 50 incinerators in Chicago. Of the 50 samples, only 18 met an environmental standard for the concentration of a hazardous compound. Can it be conclu
