The choice of co-sleeping or independent sleeping is a good example of a custom complex, and the underlying cultural beliefs because in some of the culture, co-sleeping is considered as a bad habit and prohibited by the culture but encourages independent sleeping while on the other hand, some culture allows the co-sleeping due to no prohibition in their cultural believes so we can say that custom complex is responsible for this choice of sleeping.

Mrac [35]

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

r=\frac{sum(x-xbar)(y-ybar)}{\sqrt{sum(x-xbar)^2sum(y-ybar)^2} }

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=\frac{-6}{\sqrt{23.2(8)} }

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.

kolbaska11 [484]

The fact that shops should be prohibited to sell any food or drinks that have been scientifically proven to be bad for people's health is highly disagreeable.

<h3>What is the significance of prohibition?</h3>

If any food is bad for people, proven by scientific studies, it should be banned for even production by the food administration authorities. Because unless authorities do not ban the production, prohibition for their sell at shops really makes very less to zero sense.

Therefore, the significance regarding of prohibition has been aforementioned.
