The mean of the sample is 0.97 while the standard deviation of the sample is 0.015.

<h3 /><h3>What is the average density?</h3>

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 $0.96 + 0.99 +0.95/3 = 0.97$

The standard deviation is obtained from;

s= $\sqrt{(0.96 - 0.97)^2 + (0.99 - 0.97)^2 + (0.95 - 0.97)^2/(3 - 1)}$

s = $\sqrt{(0.0001) + (0.0004) + (0.0004)/2}$

s = 0.015
