Question

Imagine that a researcher conducts a study and fails to find a statistically significant correlation between exercise and weight loss. However, there is a real association between exercise and weight loss in the population. What kind of error has this researcher made? a. draw a person so that the psychologist may determine which parts are left out or exaggeratedb. describe their perceptions of the causes of people's behavior so that the psychologist can measure attributional complexityc. describe their current level of hostility so that the psychologist can measure their type A tendenciesd. tell stories about pictures that the psychologist shows them

Answer 1

Answer:

Type II error was made

Explanation:

I will start by stating the null and alternate hypothesis

Null hypothesis

H0: there is no significant correlation between exercise and weight loss

Alternate hypothesis

H1: there is significant correlation between weight loss and exercise.

This researcher has made the mistake of accepting a false null hypothesis Instead of the alternate hypothesis as the question says that there is significant correlation between exercise and weight loss. A type II error has therefore been made.

A type II error is an error of omission and it occurs when the alternate hypothesis is rejected and the null hypothesis is accepted.

please note that the multiple choice options that were added to the question is not related to the question that was asked in anyway and must have been a mistake.
