I believe this is called scaling. This is the word that I am associating with your definition, as well as what many internet sources say. I am not 100% sure, but I think this is correct. Hope this helps.

Step-by-step explanation:

Test Statistics <em><u>(which is a random variable that is been computed and calculated from a set of data sample and used in a hypothesis test. A test statistics can be used to determine whether to reject the null hypothesis.) </u></em>would follow a F distribution

Test Statistics = Mean Square Between / Mean Square Within = 154.1 / 34.6 = 4.45

Flying against the wind, an airplane travels 4560 kilometers in 6 hours. Flying with the wind, the same plane travels 3720 kilom

Flura [38]

Answer:

The speed rate of the plane in still air is 1006.67 km/h

The speed rate of the wind is 246.67 km/h

Step-by-step explanation:

To answer the question, we let the speed of the plane in still air = x km/h

Let the speed of the wind = y km/h

Therefore,

4560/(x - y) = 6 hours and

3720/(x + y) = 3 hours

4560 = 6·x - 6·y.........(1)

3720 = 3·x + 3·y ........(2)

Multiplying equation (2) by 2 and add to (1) gives

12080 = 12·x

x = 12080/12 = $1006\frac{2}{3}$ km/h

Substituting the value of x in (1) gives

4560 = 6040 - 6·y

6·y = 1480

y = 1480/6 = $246\frac{2}{3}$

The speed rate of the plane in still air = 1006.67 km/h

The speed rate of the wind = 246.67 km/h.
