Confidence Intervals
... those needed for the case when σ is unknown (t*). z*, depends only on the level of confidence, t* depend on both the level of confidence and on the sample size (for example: the t* used in a 95% confidence when n=10 is different from the t* used when n=40). ...

(a) Yes (b) No because no differences if =0 which falls in between the limits of the confidence interval ...
