The sample standard deviation is, 4.211232926 found by 17.73448276. As we note again
that the sample variance is in terms of per price of 500mg of Royal Seal Salt, but taking the
square root of 17.73448276 gives us 4.211232926, which is in the same unit as the original
data.

= 381
30
= 12.7
In order to get the mean, we have to add all the collected Data price of 500mg of Royal Seal Salt and divide by 30, that is why we get the 12.7 in total.
