... • Sometimes we are not interested in a confidence interval for a population parameter but rather we are interested in a prediction interval for a new observation. • For our light bulb example, we might want a 95% prediction interval for the time a new light bulb will last. • For our paint example, w ...

The Lighthouse Problem Revisited
... translate these indices into μ and x values using my previously defined x vector for μ and z vector for x. I found that the ML estimator for μ does approach μ as n increases. In Figure 6, the f(x) value of the graph is the ML estimate after the first x of the 100 samples have been used to compute th ...

Since, under very general assumptions, the sampling distribution of the mean is well approximated by a Normal distribution, the range for which one would be comfortable ...
