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.
In order for the relationship between price and quantity demanded to shift, (known as the level of demand), the thing that would need to take place is that Consumer income increases.
<h3>What is the Understanding of Quantity Demanded?</h3>
The price of a product or services and that of quantity demanded for that given product is known to have an association that is said to be an inverse relationship.
Note that this inverse relationship connote that higher prices leads to in lower quantity demand as well as lower prices leads to higher quantity demand.
Therefore, In order for the relationship between price and quantity demanded to shift, (known as the level of demand), the thing that would need to take place is that Consumer income increases.

Culture influences the daily state of society and its direction of development, while politics determines the nature and form of culture and has the function of transforming it. Therefore, politics has a decisive role in deciding which direction the culture is going to develop. Culture is the basis for shaping social normalcy and development.
