Solution:

If the confidence interval for the standard deviation is between 4 and 16 then the confidence interval for the variance will be between 16 and 256.

Explanation: If the confidence interval for is given by :

4< <16

then the confidence interval for 2 will be given by:

42<2<162

16<2<256
