(Solved): 1- The formula below is =Nx2(x)2/N 2- The formula below is (2 points) CV=10 ...

1- The formula below is $?=\sqrt{\frac{?x^2?(?x{)}^2/N}{N}}$ 2- The formula below is (2 points) $CV=\frac{?}{?}\times 100$ The formula below is (2 points) $s^2=\frac{?(x?\stackrel{?}{x}{)}^2}{n?1}$ 6- The formula below is (2 points) $r=\frac{n?xy?(?x)(?y)}{\sqrt{n?x^2?(?x{)}^2}\sqrt{n?y^2?(?y{)}^2}}$ 7. The formula below is (2 points) ${\stackrel{?}{R}}^2=1?\frac{(SSR/(n?k?1))}{(SST/(n?1))}=\text{ adjusted }{R}^2$ 8- The formula below is (2 points) $?=\sqrt{npq}$ 10-Explain what is the concept behind the example below. (4 points) OR 11-Explain the equations below: (4 points) $\begin{array}{c}y={?}_0+{?}_1{x}_1+\dots +{?}_k{x}_k+u\\ ?E(y?x)={?}_0+{?}_1{x}_1+\dots +{?}_k{x}_k\end{array}$
