The mean deviation of the ratings is 4.12
<em><u>Explanation</u></em>
The ratings of the ten experts are: 34, 35, 41, 28, 26, 29, 32, 36, 38 and 40
So, the mean of all ratings ![=\frac{34+35+41+28+26+29+32+36+38+40}{10}= \frac{339}{10}=33.9](https://tex.z-dn.net/?f=%3D%5Cfrac%7B34%2B35%2B41%2B28%2B26%2B29%2B32%2B36%2B38%2B40%7D%7B10%7D%3D%20%5Cfrac%7B339%7D%7B10%7D%3D33.9)
<u>The formula for Mean deviation</u>
, where
is the given data from
to
,
is the mean of the data and
is the total number of data. So.....
![|x_{1}-\mu |= |34-33.9|=0.1\\ |x_{2}-\mu|=|35-33.9|=1.1\\ |x_{3}-\mu |=|41-33.9|=7.1\\ |x_{4}-\mu |=|28-33.9|=5.9\\ |x_{5}-\mu |=|26-33.9|=7.9\\ |x_{6}-\mu |=|29-33.9|=4.9\\|x_{7}-\mu |=|32-33.9|=1.9\\ |x_{8}-\mu |=|36-33.9|=2.1\\ |x_{9}-\mu |=|38-33.9|=4.1\\ |x_{10}-\mu |=|40-33.9|=6.1](https://tex.z-dn.net/?f=%7Cx_%7B1%7D-%5Cmu%20%7C%3D%20%7C34-33.9%7C%3D0.1%5C%5C%20%7Cx_%7B2%7D-%5Cmu%7C%3D%7C35-33.9%7C%3D1.1%5C%5C%20%7Cx_%7B3%7D-%5Cmu%20%7C%3D%7C41-33.9%7C%3D7.1%5C%5C%20%7Cx_%7B4%7D-%5Cmu%20%7C%3D%7C28-33.9%7C%3D5.9%5C%5C%20%7Cx_%7B5%7D-%5Cmu%20%7C%3D%7C26-33.9%7C%3D7.9%5C%5C%20%7Cx_%7B6%7D-%5Cmu%20%7C%3D%7C29-33.9%7C%3D4.9%5C%5C%7Cx_%7B7%7D-%5Cmu%20%7C%3D%7C32-33.9%7C%3D1.9%5C%5C%20%7Cx_%7B8%7D-%5Cmu%20%7C%3D%7C36-33.9%7C%3D2.1%5C%5C%20%7Cx_%7B9%7D-%5Cmu%20%7C%3D%7C38-33.9%7C%3D4.1%5C%5C%20%7Cx_%7B10%7D-%5Cmu%20%7C%3D%7C40-33.9%7C%3D6.1)
So, the Mean deviation ![=\sum \frac{|x_{i}-\mu |}{N}=\frac{0.1+1.1+7.1+5.9+7.9+4.9+1.9+2.1+4.1+6.1}{10} = \frac{41.2}{10}=4.12](https://tex.z-dn.net/?f=%3D%5Csum%20%5Cfrac%7B%7Cx_%7Bi%7D-%5Cmu%20%7C%7D%7BN%7D%3D%5Cfrac%7B0.1%2B1.1%2B7.1%2B5.9%2B7.9%2B4.9%2B1.9%2B2.1%2B4.1%2B6.1%7D%7B10%7D%20%3D%20%5Cfrac%7B41.2%7D%7B10%7D%3D4.12)

Step-by-step explanation:
Yes she do break even because let me show you a expression now take a number line and then you start at -16 right and then you go down the number line and then this is how it go -16 -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 and i just answer your Q there you go -16+16=0
