a budget opportunity beacause hes problem is budget
Answer:
Strong positive
Explanation:
In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.
- Two variables have a positive correlation when if one increases the other increases too.
- Two variables have a negative correlation when if one increases the other decreases and vice versa.
Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.
In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>
Thus, Isabella would conclude that this is a strong positive relationship.
Ethnic Enclaves is the correct asnwer.
Throughout history, we see immigrants moving from one place to the other and often staying in neighborhoods with people with whom they shared the same nationality, culture and similar habits. In Sociology and Anthropology, an ethnic enclave is defined as a geographic area where a community that shares similar background maintains a strong sense of identity and customs from their place of origin. These ethnic enclaves were the most common option for these immigrants since they felt more welcome and safer from prejudice and discrimination.
Answer:
<em>The correct option is C) imagination inflation</em>
Explanation:
Imagination inflation can be described as a situation in which imagining a situation that never occurred is done with such frequency that the person starts believing that the scenario of his imagination actually occurred.
As Nadine's younger brother starts to imagine himself dialing the phone when he was younger hence this is an example of imagination inflation.
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.
