Simplify the expression. picture provided. .

Step-by-step explanation:

Remember the following:

- The Product of powers property:

- The Quotient of powers property:

- And the Negative exponent rule:

Therefore, having the expression , you can simplify it by applying the properties mentioned before.

Then, you get:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
