2.3.10 In Example 1.1, we looked at a study to investigate whether dolphins could communicate. In doing so, we tested whether Buzz, one of the dolphins, could push the correct button more than 50% of the time in the long run. a. Describe what a Type I error would be in this study. b. Describe what a Type II error would be in this study.

a. When we reject null although it was true.

b. When we fail to reject null although it was false.

Explanation:

A type I error occurs when we reject a null hypothesis when it is actually true.

Thus in this case Type I error will occurs when we have a strong evidence that Buzz a dolphin could communicate. But we still reject this and conclude that it cannot communicate and we are only guessing.

Type II error occurs when we fail to reject a null hypothesis although it is false. So when we do not have a strong evidence that Buzz the dolphin can communicate and we still conclude that it can, it is said that we have incurred type II error.

disorders of the brain include both behavior disorders and other psychiatric illnesses. the primary difference between a behavior disorder and another type of psychiatric disorder is the presence of choice. psychiatric conditions are considered to be involuntary while in behavior disorders, choices are essential.
