Answer: There is a strong association between age and weight.
Step-by-step explanation:
The correlation coefficient (r) is used to describe the relationship between two variables.
If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.
Here, Variables: Age and weight.
correlation coefficient = 0.512
That means, there is a strong association between age and weight.
Answer:
Step-by-step explanation:
From a sketch of the given coordinates, you notice that the ellipse has its center at (0,0) i.e origin
It is a vertical ellipse centered at (0,0),
The major axis has its coordinates at (0,a) = (0,5) and (0,-a) =(0,-5)
The minor axis has it coordinates at (0,b)=(0,-2) and (0,2)
Here a>b
The length of major axis is 2a = 2*5= 10
The length of minor axis is 2b= 2*2=4
Equation is given by
