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:
set point theory
Explanation:
Set point theory: The term "set point theory" is described as a phenomenon that suggests that an individual's body weight is being regulated at a preferred or predetermined level through a "feedback control mechanism". However, in an adult, body weight is being maintained at some "relatively stable level" for quite a long period in time. In other words, it refers that an individual's body will fight to "maintain" a specific body weight.
In the question above, the given statement illustrates the set point theory.
Circumstances that increase anonymity are likely to reduce stress.
Galileo was tried and sentenced to house arrest by the Catholic Church because he expressed support for the Heliocentric Theory of Copernicus, which states that Earth and all the other planets revolve around the Sun, and this theory was greatly opposed by the Catholic Church, which believed in the Geocentric model of the Solar System (The Sun and all the other planets revolve around the Earth).
