question
based on the following calculator output, determine the population standard deviation of the dataset, rounding to the nearest 100th if necessary.
1 - var - stats
$\bar{x}=245.66666666666666$
$sum x = 19162$
$sum x^{2}=4759062$
$sx = 25.886197830025907$
$sigma x = 25.719725377699376$
$n = 78$
$minx = 179$
$q_{1}=223$
$med = 248$
$q_{3}=267$
$maxx = 306$

Explanation:

Step1: Identify the population standard - deviation symbol

In statistics, $\sigma x$ represents the population standard deviation. The calculator output gives $\sigma x = 25.719725377699376$.

Step2: Round the value

We need to round the value of $\sigma x$ to the nearest hundredth. Rounding 25.719725377699376 to the nearest hundredth gives 25.72.

Answer:

25.72
