we know that
<u>The correlation coefficient</u> is a number between and
that represent the linear dependence of two variables or sets of data
Using the function CORREL in a excel tool, calculate the correlation coefficient (r)
see the attached table
the correlation coefficient for the data in the table is equal to
therefore
<u>the answer is</u>
Answer:
Only A, E, and F are correct.
Step-by-step explanation:
The difference between two points is , thus the difference between the height of the Pelican and the height of the Heron is
, and between the Pelican and the trout it is
.
The distance between two points is just the absolute value of the difference between them. Between the Pelican and the Heron it is, and the distance between the Pelican and the Trout is
.
Therefore,
A is correct;
B is incorrect (difference is not positive);
C is incorrect (distance cannot be negative);
D is incorrect (difference is not positive);
E is correct;
F is correct;
