(a) Construct a \( 98 \% \) confidence interval about \( \mu \) if the sample size, \( n \), is 12 .
(b) Construct a \( 98 \% \) confidence interval about \( \mu \) if the sample size, \( n \), is 17 .
(c) Construct a \( 99 \% \) confidence interval about \( \mu \) if the sample size, \( n \), is 12.
(d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
