Question:
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.
