Answer:
Step-by-step explanation:
Given that a pie chart shows data as
Excellent 7%
Good 44%
Fair 35%
Poor 13%
Other 1%
If 4 people are chosen at random we find that each person is independent of other and there are two outcomes either excellent or not excellent.
p = Prob for success = p = 7%=0.07
q = Prob for non success = 1-0.07 = 0.93
If x is a random variable representing the excellent persons then X is binomial with n =4, p = 0.07
Required probability = P(X=4)
=
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
Let
Using the function CORREL in a Excel tool
Find the correlation coefficient for the set of data
see the attached table
the correlation coefficient is 
therefore
<u>the answer is the option B</u>
