A new motorcycle is being developed to meet new gas mileage standards recently passed by the federal government. An engineer tested three model designs by randomly assigning the motorcycles in a blind study (the riders recorded the mileage but did not know the design of the motorcycle, only its code). The data in miles per gallon (MPG) for the three designs is listed below: X-1 B-1 Z-1 45 55 54 62 55 52 50 54 41 65 44 35 62 52 38 50 69 41 50 58 51 58 45 44 Using StatCrunch, determine the means for the three groups and compute the sums of squares, degrees of freedom, and mean squares for these data. What are the hypotheses to be tested here? What is the value of F? Using an alpha of 0.05, is the F statistic significant? Why? Copy and Paste your work from StatCrunch into your Word document submission for full credit.
A single-stage ideal regenerative steam cycle has a boiler pressure and temperature of 5000 kPa and 500 C, and a condensing pressure of 10 kPa. The extraction pressure is 500 kPa.
An air-standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes: Isentropic compression from 100 kPa and 27 degrees C to 1.11 MPa. P = constant heat addition in amount of 3,020 kJ/kg
