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.
Answer:
Competition
Explanation:
Positioning strategy that focus on competition will try to create a perception that the product offer some sort of value that make it better compared to other competition.

A system of government in which power is divided between a central government and regional governments is known as Federalism.
<h3>What is Federalism?</h3>
- In a single political system that divides the authorities between a general administration and regional governments, federalism is a mixed or compound form of government.
- The Old Swiss Confederacy's unions of states were where modern federalism was first implemented.
- Although the United States government is known for its federalism, other countries also have this style of government. Canada, for instance, has a federalist administration.
- In Canada, there are ten different provincial governments in addition to the federal government.
- In a federated form of government, two levels of government share jurisdiction over the same territory. The wide governance of more expansive geographical areas is typically the purview of an overarching national government.
