Advantages: Empirical methods mean those which use experimentation to determine or estimate actual values, be it frequencies ("how many") or relative proportions. This is good because these experiments are observable, able to be confirmed, and easily replicated.

Disadvantages: Too often, short run experiments (too few number of trials) result in invalid conclusions. E.g. if you flip a coin 5 times and get 4 heads, you might think you'll get heads 80% of the time, but in reality if you flipped the coin millions of times, you'd get closer to 50% (depending on how the coin is weighted).

What are the differences between sampling error and sampling bias?

Sampling bias is a known or unknown selection of data to be examined in an audit. There should be no bias if the sample is random. Ex ... look at the first item in the file folder. or examine all files for purchases over $10,000, or examine no files for sales less than $500. Sampling error, is the incorrect selection of files for an audit. Ex ... a random number generator tells you to audit file 1547, but you select 1457. Sampling error is also used to describe the fact that auditing a sample will NOT create the exact same answer as auditing every single file or transaction.

True or False As the amount of confidence increases the required sample size should decrease Explain your answer?

I can examine this as a question of theory or real life: As a matter of theory, I will rephrase your question as follows: Does theoretical confidence interval of the mean (CI) of a sample, size n become larger as n is reduced? The answer is true. This is established from the sampling distribution of the mean. The sampling distribution is the probability distribution of the mean of a sample, size n. I will also consider the question as a matter of real life: If I take a sample from a population, size 50 and calculate the CI and take a smaller sample, say size 10, will I calculate a larger CI? If I use the standard deviation calculated from the sample, this is not necessarily true. The CI should be larger but I can't say in every case it will belarger. The standard deviation of the sample will vary from sample to sample. I hope this answers your question. You can find more information on confidence intervals at: http://onlinestatbook.com/chapter8/mean.html
