Note: It'll be better if you can write properly such as writing "95% CI for the population variance, sigma^2 is..." Hence, the "95% CI for the population sd, sigma is..."

*Checked. The solution steps and answers are all correct.

However, a better justification for part (b) should be "because the CI contains zero". 

Although your statement sounds similar to what I suggested above, but the implications are different. 

Anyhow, at your level, your statement in (b) can be accepted.

Well done.
