Consider a sample of blades for a circular saw. Their diameters are measured and found to have a variance of 2.42. Give a point estimate for the population variance in diameters of blades for a circular saw. Round your answer to two decimal places, if necessary.

2.42

Step-by-step explanation:

We are asked to consider a sample of blades for a circular saw, and their diameters were measured.

We are told they have a sample of variance, S²= 2.42

We are told to give a point estimate for the population variance in diameters of blades for the circular saw.

The sample variance, S² can be said to be a point estimate of the population variance.

Therefore, it can be said that the sample variance, S² is a point estimate for the population variance, b².

Which can also be written as:

b² = S²

b² = S² = 2.42

• The point estimate for the population variance is 2.42
