Question

When the researcher analyzes her data, the computer prints out (p = .67). If the researcher tested for statistical significance at p is less than or equal to .05, what does p = .67 mean in relation to the null hypothesis? In relation to the research hypothesis Null hypothesis decision – Research hypothesis decision –

Answer 1

If a probability of obtaining a sample Mean is less than 5% (0.05) when the null is true, then reject the null hypothesis .

If the probability of obtaining a sample mean is greater than 5%(0.05) when the null is true and then retain the null hypothesis.

Here p value is P=.67 which is greater than the significance level .We can not reject the null hypothesis .

Null hypothesis is a hypothesis that says there is no significal significance between the two variables.

It is usually a hypothesis an experimenter will try to disprove.

Research hypothesis is aspecific, clear, and testable proposition or predictive statement about the possible outcome of a scientific research study  based on a particular property of a population, such as presumed differences between groups on a particular variable or relationships between variables.
