We have a normally distributed random variable Y and we wish to develop a 95% confidence interval for the variance of Y. We obtain a random sample of 10 elements and we have obtained the data Y = 2, 3, 3, 4, 5, 5, 6,7,7, 8. It can be seen that the mean value of the data is 5 and the sample standard deviation is 2. Give the 95% confidence interval for the variance of Y. 3.57 to 6.53 1.89 to 13.33 2.13 to 10.93 3.84 to 6.16 1.64 to 8.39
