The results on a computer aptitude test for a sample of 10 individuals are:

X-bar = 65 and s2 = 78

Calculate the confidence interval on the variance of this population. Use a 95% confidence level.

Options from question 26 :

P(33.90 2 256.96) = 0.95

P(19.02 2 259.96) = 0.95

P(2.70 s2 19.02) = 0.95

P(19.02 s2 259.96) = 0.95

P(36.90 s2 259.96) = 0.95

P(36.90 2 259.96) = 0.95

P(2.70 2 19.02) = 0.95
