-This experiment randomly samples from a N(μ=0, σ<sup>2</sup>=1) distribution and constructs a confidence interval for the mean (μ). Note how confidence interval widens as the confidence level increases. This is counterbalanced by the sample-size increase. Also, see the effect of the confidence level, 100(1-α)%, on the frequency of intervals missing the estimated parameter (μ=0, in this case).
