WebThe range of the interval would decrease when comparing the 99% confidence interval to the 90% confidence interval. ... Both distributions are symmetric. Both distributions have infinite tails. Differences: The t-distribution has more spread than the standard normal distribution, meaning that it has fatter tails and a flatter peak. WebSep 8, 2016 · The simulation method has three steps: Simulate many samples of size n from the population. Compute the confidence interval for each sample. Compute the proportion of samples for which the (known) population parameter is contained in the confidence …
