Question

based on the following calculator output, determine the mean of the dataset, rounding to the nearest 100th if necessary.
1 - var - stats
$\bar{x}=79.41104294478528$
$sigma x = 12944$
$sigma x^{2}=1045816$
$sx = 10.517316738345745$
$sigma x = 10.485005397045338$
$n = 163$
$minx = 51$
$q_{1}=71$
$med = 80$
$q_{3}=87$
$maxx = 104$

Explanation:

Step1: Identify the mean value

The symbol $\bar{x}$ represents the mean in statistics. The calculator output gives $\bar{x}=79.41104294478528$.

Step2: Round the mean

We need to round to the nearest hundredth. Looking at the thousand - th place (the third digit after the decimal), which is 1. Since 1 < 5, we keep the hundredth - place digit as it is.

Answer:

$79.41$
