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:
A. the Industrial Revolution.
Explanation:
When one begins to study the Industrial Revolution, the first question to raise is what kind of revolution we are talking about. Often we understand the word "revolution" as a revolt, a dispute between political groups, or even a civil war in a given society. But that is not the point here.
The meaning we use in this case is that of revolution as a profound transformation, a very big change, a break from what was before. When we speak, then, of an "industrial revolution", we are talking about a drastic change in the way man-made products are manufactured, this change has been so strong that we can say that the changes in technology that underlie sustained growth that we observed today began at that time.
