Answer #1

Yes Q 12 as well as Q 15 both are false statements.

90% CI narrower than than the 99% CI

And if 99% confidence interval doesn't contain your true mean value then 95% is narrower than 99% therefore it also doesn't contain the true mean value.

Everything is right in above questions.

Keep it up...
