The set of all values of the test statistic that lead us to reject the null hypothesis is called the rejection region or critical region. On the contrary, the set of values of the test statistic that make us not reject the null hypothesis is called the acceptance region.

## What is the zone of acceptance and rejection?

Critical or rejection region: It is the set of values of the contrast statistic that leads us to the decision to reject the null hypothesis. Acceptance region: It is the set of values of the contrast statistic that leads us to the decision to accept the null hypothesis.

## What does the rejection of a hypothesis mean and what does it imply?

A null hypothesis is an assumption that is used to deny or affirm an event in relation to one or more parameters of a population or sample. It is the hypothesis that the researcher intends to reject. … If you have enough evidence for it, you will be able to prove that the opposite is true.

## How to know if a hypothesis is accepted or rejected?

How to know if a hypothesis is accepted or rejected?

- If the null hypothesis is to be accepted: “There is no evidence to reject the null hypothesis”.
- If the null hypothesis is to be rejected: “There is sufficient evidence to reject the null hypothesis.”

## What is an accepted hypothesis?

For a hypothesis to be accepted as scientific, it must be something that can be supported or refuted through the collection of information through methodologically validated research techniques, and its subsequent analysis.

### When a null hypothesis is accepted is it possible that?

In the first instance, accepting the null hypothesis does not allow for any substantive conclusions. Furthermore, if the p-value is significant, only a single value is excluded as a plausible value for the parameter.

### How do you reject a scientific hypothesis?

). The research hypothesis is a special statement whose validity is intended to be demonstrated, and if the empirical evidence does not strongly support the research hypothesis, then the null hypothesis will be accepted, abandoning the research hypothesis.

### What is the null hypothesis in an investigation?

A hypothesis is an assumption of something, in statistics we work with hypotheses as an affirmation of facts that happen in the population studied. The null hypothesis is the statement contrary to what we take as a hypothesis, this second called the alternative hypothesis.

### How do we determine the critical region in a hypothesis test?

The area of the critical region is equal to the size of the type I error. To construct an appropriate decision rule in testing a statistical hypothesis, it is necessary to establish an alternative hypothesis that reflects the value or range of possible values of the parameter, if the null hypothesis is false.

### How to interpret the results of the Student’s t-test?

Student’s t-test is a type of inferential statistics. It is used to determine if there is a significant difference between the means of two groups. With all deductive statistics, we assume that the dependent variables have a normal distribution.

### When is the null hypothesis test F rejected?

F Statistic: Variation Between Sample Means / Variation Within Samples. The F statistic is the test statistic for F tests. … To reject the null hypothesis that the group means are equal, we need a high F value.

### When is the null hypothesis rejected in Anova?

As for one-way ANOVA, you reject the null hypothesis when there is enough evidence to conclude that not all means are equal.

### What is a critical value?

A critical value is a laboratory result whose finding indicates a risk to the life of a patient, so that its communication for the adoption of immediate measures is peremptory.

### What are the types of hypotheses?

There are different types of hypotheses: the research or working hypothesis, the alternative hypothesis, the null hypothesis or the statistical hypothesis. However, it is possible for an investigation to have more than one hypothesis.

### How do you refute a hypothesis?

Therefore, if the premises are well established, the hypothesis must be rejected. In other words, the hypothesis is refuted. And it only means that, that the hypothesis is refuted. Which does not support a rival hypothesis that should be, in any case, subject to testing on their part.

### What is the acceptance or rejection of the hypothesis in the scientific method?

Verifiability: It is the confirmation or rejection of the hypothesis. Hypotheses are verified or rejected by means of the experimental method. Hypotheses or supposed answers to our problems are proposed and this is confirmed or restructured according to the results presented during the experimentation.

### How to refute a hypothesis examples?

Refutation

- Rebuttal is finding the error in a general argument and explaining it by the use of citations, reasons, or evidence. …
- Hypothesis (H): “all swans are white” and “in my garden there is now a swan” …
- Conclusion (C): “The swan in my garden is white”…
- No Conclusion (¬C) : “The swan in my garden is black”

### When is a Chi square null hypothesis accepted or rejected?

If the p-value is less than or equal to the significance level, you reject the null hypothesis and conclude that there is a statistically significant association between the variables.

### How to write a hypothesis examples?

Tips for learning how to write a hypothesis

- The question comes first. Before formulating a hypothesis, you must clearly identify the question you are interested in studying.
- A hypothesis is a statement, not a question. …
- Make it clear. …
- Consider the variables. …
- Make sure your hypothesis is “testable.”

### When is Fisher’s F used?

The F distribution is also known as the Fisher-Snedecor distribution, after statisticians Ronald Fisher and George Snedecor. … More specifically, an F distribution is used when seeking to study the ratio of the variances of two normally distributed populations.

### When should an F-ratio test be used?

In statistics, Snedecor’s F test is any test in which the statistic used follows an F distribution if the null hypothesis cannot be rejected.

### What happens when Student’s t is negative?

Goodness of fit.

The Student’s t-distribution is symmetric, like the normal distribution, but it is flatter, that is, its coefficient of kurtosis or pointedness is negative. When the sample size exceeds 30 or 35 cases, the Student’s t approximates the normal distribution.
