It was experimentally determined from three trials that an object had a density of 0.96, 0.99, and 0.95 g/mL. What is the average density and standard deviation of this object

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

What is the average density?

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
