Answer:
The F-Ratio increases as, the variability between means increases relative to the variability within groups
Step-by-step explanation:
The F-Ratio is given as follows;
Where;
= The variance between groups
= The variance within groups
Therefore, as the F-Ratio increases, the variability between groups (means) increases relation to the variability within groups
The volume of railway car is 216 cubic meters
<em><u>Solution:</u></em>
Given that, Railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters and a height of 4 meters
To find: volume of railway car
<em><u>The volume of rectangular prism is given as:</u></em>
Where,
"l" is the length and "w" is the width and "h" is the height of prism
From given question,
length = 18 meters
width = 3 meters
height = 4 meters
Substituting the values, we get
Thus volume of railway car is 216 cubic meters
