Answer: sigma is used for measuring Population Standard Deviation.
Step-by-step explanation:
The lower case Greek letter 'sigma' is denoted by the symbol ( 
).
This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol 
.
Formula for Population Standard deviation ( ) is = 
,
where 
= each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
we conclude that the store where you can get more sausages is in Peter the Butcher.
<h3>
Which shop is the best option?</h3>
You have £10.
Peter the Butcher sells 6 sausages for £2.30
The number of packages that you can buy is:
£10/£2.30 = 4.3
Rounding down to the next whole number, we conclude that here you can buy 4 packages, then:
4*6 = 24 sausages
4*£2.30 = £9.20
So here you can buy 24 sausages for £9.20
In Paul the butcher, you can buy 10 sausages for £3.50
Notice that here you can only buy 2 packages (because the cost of 3 packs would be £10.50, which is more than the amount you can spend).
Then here you only can get 20 sausages.
Then, we conclude that the store where you can get more sausages is in Peter the Butcher.
