Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
Insane is a psychological term used to describe individuals with a severe mental disorder. This statement is False.
The definition of insanity is doing constant issue over and over and expecting totally different results." No, it isn't.
To be clear, the mental disease could be a legal term touching on a defendant's ability to work out right from wrong once a criminal offense is committed that an individual cannot distinguish fantasy from reality.

Answer:
Consistency
Explanation:
In psychology, the term behavioral consistency refers to the tendency that people have to behave in a similar manner to the one in which they behaved in the past or in another environment. In other words, we can predict how people will behave based on its previous behaviors because there's a consistency to it.
In this example, <u>Sally is shy when she is in class, with friends and when she is with her family. </u>Therefore, we can see that there is a consistency in her behavior and <u>she tends to act in pretty much the same way no matter the environment. </u>Thus this example demonstrates the concept of behavioral consistency.
