WebAs the sample size $n$ increases, the length of the interval decreases. The moral of the story, then, is to select as large of a sample as you can afford. As the confidence level decreases, the length of the interval decreases. (Consider, for example, that for a 95% interval, $z=1.96$, whereas for a 90% interval, $z=1.645$.) WebNov 8, 2024 · First, the confidence interval is thinner for median income values of 2 through 5 and wider at more extreme values. This is because, for most records in the data, the income is somewhere between 2 and 5. For such cases, the model has more data, hence the sampling uncertainty is smaller.
