A sample of 15 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the population standard deviation. Round your answer to three decimal places. 1.33,1.25,1.22,1.27,1.39,1.34,1.33, 1.32,1.26,1.20,1.28,1.20,1.24,1.38, 1.31

The point estimate for the population standard deviation is of 0.061.

Step-by-step explanation:

The point estimate for the population standard deviation is the sample standard deviation.

Sample mean:

Sample standard deviation:

Square root of the sum of the difference squared of all these values (1.33, 1.25, 1.22,...) and the mean of 1.288, divided by 15 - 1 = 14.

Using a calculator, it is of:

The point estimate for the population standard deviation is of 0.061.
