Which or the following is not a possible value for the correlation coefficient (r)?
2 answers:
<h3>Answer: A) 2</h3>
Explanation:
The correlation coefficient r has this range of values
which can be stated as "r is between -1 and 1, including both endpoints".
As you can see, r = 2 is outside this range and not a possible correlation coefficient. The largest r can get is r = 1 to indicate perfect positive linear correlation.
On the other end of the spectrum, r = -1 means perfect negative linear correlation. In between, r = 0 means no linear correlation at all.

Step-by-step explanation:
In the picture attached, the Truth Table for the operator “OR” is shown. With it we can compute the next table:
p q ∧ r p ∨ (q ∧ r)
T T T
T F T
F T T
F F F
We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.
The only row from the table of the question that satisfies this criterion is row E.
