Short tandem repeats (STRs) are short repeated sequences of DNA (1–10 bp) that account for approximately  3% of the human genome.

Usually, the significance level or the probability of type i error is set to 0.05(5%), assuming that it is satisfactory to have a 5% probability of inaccurately rejecting the null hypothesis.

A type II error appears when the null hypothesis is false but mistakenly fails to be refused.

A type II error is also known as false negative (where a real hit was rejected by the test and is observed as a miss), in an experiment checking for a condition with a final outcome of true or false.

A type II error is assigned when a true alternative hypothesis is not acknowledged. In other words, an examiner may miss discovering the bear when in fact a bear is present (hence fails in raising the alarm).

Again, H0, the null hypothesis, consists of the statement that, “There is no bear”, wherein, if a wolf is indeed present, is a type II error on the part of the investigator.

The relationship between truth or false of the null hypothesis and outcomes or result of the test is given in the tabular form.
