Answer 2

2.5768

Step-by-step explanation:

• The most widely used measure of the spread of values in distribution is the standard deviation of the mean (SD).
• The square root of the variance is used to compute SD (the average squared deviation from the mean).
• Variance in a population is:

                             $\sigma^2 = \frac{\Sigma (x-\mu)^2}{n}\\\\where\\\\x \ is \ a \ value \ from \ the \population, \\\mu \ is \ the \ mean \ of \ all \ x, \\n \ is \ the \ number \ of \ x \ in \ the \ population, \\\Sigma \ is \ the \ summation$
