Answer:
B. it is often transitory—that is, it is brief and passing.
Explanation:
There are lots of different kinds of collective behavior, so trying to identify a specific set of standards or reasons to suit all is very difficult. Also, episodes of collective behavior —such as riots, social panic, and more— are unpredictable and last for a short time, which represents a difficulty for sociologists who want to analyze them as they take place. People involved in these events are often strangers to each other, making it even harder to determine who took part in them.
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.
The intended purpose of federal legislation such as the 1947 Taft-Hartley Act is to increase the power of labor unions to negotiate for fair wages.
option A is the correct answer.
<h3>What is 1947 Taft-Hartley Act?</h3>
