Normalization is a method for analyzing and reducing a relational database to its most streamlined form to ensure minimum redundancy, maximum data integrity, and optimal processing performance

The process of organizing a given dataset is called normalization. For normalizing a given data the date is first divided into tables and then the tables are studied to establish the relationship between them. It helps to remove the duplicate values, & insert and update anomaly.

Normalization can be done in three steps-

1. First normal form

2. Second normal form

3. Third normal form

The top 20% percent of U.S. households receive approximately 86% of the total U.S. Income.

Explanation:

The reason that the top 20% percent of U.S. households receive approximately 86% of the total U.S. Income is that the wage divide is effected and kept up by the institutional laws and the way american businesses work.

There is not enough incentive on healthcare and welfare schemes which keeps the poor of the country poor while the rich and the upper middle class are designed to not fall off from their stature with better bankruptcy laws and pardons.

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.
