Question

Consider a sample of golf balls. Their diameters are measured and found to have a standard deviation of 0.72. Give a point estimate for the population standard deviation in diameters of golf balls. Round your answer to two decimal places, if necessary.

Answer 1

S= 0.72

Explanation:

Hello!

The parameter is σ² and the point estimation is S²

The same counts for the square root:

The parameter is σ and the point estimation is S

So if the standard deviation of a sample of golf balls was calculated and is S= 0.72, the that's the estimation point for the population standard deviation.

I hope it helps!
