For the data given in Example 8.20, find a 95% confidence interval for σ². Again, assume that the weight is normally distributed with mean μ and and variance σ, where μ and σ are unknown.

Example 8.20:

A farmer weigh s 10 randomly chosen watermelons from his farm and he obtains the following values (in lbs):

7.72 9.58 12.38 7.77 11.27 8.80 11.10 7.80 10.17 6.00

Assuming that the weight is normally distributed with mean μ and and variance σ, find a 95% confidence interval for μ.
