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.

Explanation:
Social studies is the set of sciences whose central object of study is man, his social, political, cultural, psychological actions and interactions, etc. Citizenship, on the other hand, can be understood as the set of rights and duties that an individual has when belonging to a society, such as the social and political rights that make society more just and egalitarian where all citizens have the right to have their dignity and preserved security.
Therefore, the correlation between citizenship education and social studies is the impact that each of these variables have on each other, as social studies are the basis for understanding the evolutionary process of man in society as an active subject of life construction , of their rights and well-being, where the search for social science linked to critical thinking contributes to the recognition of man and his social role, his achievements and citizenship as an essential element for human and social development.
