(A) biologically driven. the basic motivations that direct and influence human action. They deal with the most fundamental physiological requirements of man, including sex, hunger, thirst, and self-preservation.

As a result, when a person is deprived of food, drink, or oxygen or when these resources run out, an internal motivation condition is created. view drive The emerging profile has a critical role in promoting positive esthetic outcomes and preserving peri-implant stability and health. This crucial factor, which can greatly affect the integration, stability, and preservation of bone and soft tissues, should be assessed not just in terms of morphology but also as a clinical variable closely related to material properties and clinical approaches. In this way, a thorough planning strategy can be developed for this important factor. The preservation and defense of bone against contamination and infection depend heavily on soft tissue integration and adherence to prosthetic components.

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.
