The mean of the sample is 0.97 while the standard deviation of the sample is 0.015.
The average density is the sum of the density values divided by the total number of measurements.
In this case, we have three trials, the mean of the samples is [tex]0.96 + 0.99 +0.95/3 = 0.97[/tex]
The standard deviation is obtained from;
s= [tex]\sqrt{(0.96 - 0.97)^2 + (0.99 - 0.97)^2 + (0.95 - 0.97)^2/(3 - 1)}[/tex]
s = [tex]\sqrt{(0.0001) + (0.0004) + (0.0004)/2}[/tex]
s = 0.015
