To perform diagnostics on the consistency of a laboratory scale, multiple measurements are taken using a reference weight over the course of several days. The variance observed over 20 repeated measures is 248. A 99% confidence interval for the measurement variance is (122.129, 688.486). Would it be reasonable to believe that the population variance is 670?

No, because this value is too far above the sample variance of 248.

Yes, because this value is within the 99% confidence interval.

No, because a sample size of 20 is too small for estimation purposes.
