3.6.46-T Consider the following sample data for two variables. x 7 8 5 3 9 y 7 5 9 7 7 a. Calculate the sample covariance. b. Ca
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.

If an animal dies and decomposes into sediment which system spheres are interacting?
vivado [14]

Answer:

biosphere and lithosphere interaction

Explanation:

With biosphere is a term that describes the region of the earth which encompasses lives and the ecology, and lithosphere, on the other hand, lithosphere is a term that describes the earth region containing the crust and outmost layer of the earth.

Hence, in this case, when the animals dies and decomposes into smaller organic matter, that involves the biosphere, which deals with lives of organisms and the ecology, however, as those bodies decomposes, and then transforms into earth bodies, by getting absorbed into the soils, forming earth crust sediments, this involves lithosphere.

Therefore, If an animal dies and decomposes into sediment, the system spheres that are interacting are BIOSPHERE and LITHOSPHERE
