Answer: 2.04

Explanation:

We know that if population variance
$(\sigma^2)$ the sample variance
(s^2) is the best point -estimate for the the population variance
$(\sigma^2)$ .

Given : In a sample of oil filters , their diameters are measured and found to have a variance of 2.04.

i.e. Sample variance :
s^2=2.04

Then, a point estimate for the population variance in diameters of oil filters.
$(\sigma^2)$ = 2.04

Hence, the a point estimate for the population variance in diameters of oil filters= 2.04
