Question 1
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. What is a 99% confidence interval for the measurement variance of this scale?
◦
(122.129, 688.486)
◦
(11.051, 26.239)
◦
(117.809, 633.862)

Question 2
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.
