Let’s take a closer look at how this works. On the other hand, if the judge returns a guilty verdict she has concluded innocence (null) is not plausible given the evidence presented, therefore she rejects the statute of the null, innocence and concludes the alternative hypothesis- guilty. It only says that innocence is plausible because guilt has not been established beyond a reasonable doubt. show, this does not mean that the judge accepts the defendant’s claim of innocence. When the judge acquits a defendant, as on the T.V. The judge specifically stated that she did not have enough evidence to reject innocence (the null hypothesis).

Jin explained that if the judge had enough evidence to conclude the person on trial was not innocent she would have.

Like the judge in the TV show, if we have enough evidence to conclude that the null is not true, we can reject the null. So while the prosecutor has a research hypothesis, it must be shown that the presumption of innocence can be rejected. In hypothesis testing, we refer to the presumption of innocence as the NULL HYPOTHESIS. In other words, we have to believe innocence until there is enough evidence to change our mind that the person on trial is actually not innocent. legal system operates that a person is innocent until PROVEN guilty. This would be the research hypothesis guilty. In the courtroom the prosecutor is the researcher, thinking the person on trial is guilty. In most research, a researcher has a “research hypothesis”, that is, what the research THINKS is going to occur because of some kind of intervention or treatment. Jin told Carlos understanding hypothesis testing would help him understand what the judge just said. Jin asked Carlos if he had taken statistics, Carlos said he had but it was a long time ago and he did not remember a lot of it. So what is hypothesis testing and how can it help Jin explain the judge’s ruling? However, in practice, most people put more emphasis on confidence intervals as opposed to hypothesis testing, because confidence intervals estimate of specific values, but hypothesis testing is still an integral part of what we do in research. For example, we may think the difference between groups is zero and we want to see our evidence supports this guess. On the other hand, hypothesis tests require us to start with a guess (hypothesis) about what we think the value is. Confidence intervals give us an estimate of a population value when we typically do not know what the population value is. It is important to understand that confidence intervals and hypothesis tests are similar, but used for different purposes. In a courtroom in the U.S., the hypothesis test is about being innocent (remember innocent until proven guilty). Does the average number of hours worked a week really equal 40? Is the average fish caught on a weekend fishing trip really equal 4 feet (Ok, that is an attempt at a fish story)? These are examples of hypothesis testing. Much of our day to day lives involves hypothesizing about actual values. In this unit, we extend this idea of estimation to testing specific (hypothesized) values. In lesson 4, we learned about constructing confidence intervals to estimate actual population values. Let’s see if we can use the logic of hypothesis testing to help Jin respond to Carlos. She said “I do not have enough evidence to conclude you are not guilty, therefore I can NOT conclude you are guilty” Carlos turned to Jin and said, “Isn’t this the same thing as being innocent?“. In the scene, the judge handed down her conclusion.
