It would make the curve go in an upwards manner...
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:
Clause 18 from Article 1 Section 8
Explanation:
Clause 18 from Article 1 Section 8 granted the power to the government make all Laws which shall be necessary to carried out their main duties that is directly written on the constitution.
This single clause alone, granted so much flexibility for the government to create agencies and regulations that are not directly written/regulated for them within the constitution.
Example of the usage of this would be the creation The First and Second Banks of the United States, They does not necessarily written on the Constitution, but the government use it to control and regulate the economy of the nation as a whole.
Answer:
Difficult
Explanation:
In psychology, the term temperament refers to the characteristics and aspects of personality that we are born with, it is assumed to be biologically determined.
According to theorists, there are 3 different types of temperament:
- Easy: These children are generally in a positive mood, establishing quickly regular routines in infancy and adapt easily to new experiences.
- Difficult: These children tend to react negatively and cry frequently, they engage in irregular daily routines and are slow to accept new experiences.
- Slow to Warm Up: These children have a low activity level, are somewhat negative, show low adaptability and tend to display a low intensity of mood.
In the example, Joe is irritable and fussy (<u>he reacts in a negative way</u>), he doesn't do well in new situations (<u>new experiences</u>) and has irregular patterns of eating and sleeping (<u>irregular daily routines</u>), thus, we can see that the temperament Joe likely has is a difficult one.
Therefore, a developmentalist is likely to conclude that Joe has a difficult temperament.
