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.



▸

We cannot tell without more information.
