3 0

Answer:

602.6

Step-by-step explanation:

The six is in the hundreds place. Since no number is specified for the tens, a 0 goes there as a placeholder. The two, since it has no tag, is assumed to go in the ones. Another six goes in the tenths place after the decimal.

Given

The weekly salaries of a sample of employees at the local bank are given in the table below.

Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.

<h3>Variance</h3>

Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.

The mean value of the salaries of employees is;

$\rm Mean= \dfrac{245+300+325+465+100}{5}\\\\Mean=287$

The variance is given by;

$\rm Variance=\sqrt{\dfrac{(245-287)^2 +(300-287)^2 +(325-287)^2 +(465-287)^2 +(100-287)^2}{5-2}} \\\\Variance = 132.316}\\\\On \ Squaring \ both \ the \ sides\\\\Variance^2=17,507. 5$
