Question

Significance Levels and Hypothesis Testing Interpret the following p-values. Based on the p-value would you reject or retain the null hypothesis? p:05 p:07 p=.01 p=.03 Manipulation Checks Design a post-test only experiment by answering the following questions. 1. Propose a hypothesis. Remember the IV must be discrete and the DV must be continuous. 2. Operationalize the IV in order to make a treatment group. You should have at least one treatment group and one control group. However, depending on your IV, you may have more than one treatment. 3. Develop a manipulation check that you would include in the post-test to ensure you successfully manipulated the conditions.

Explanation / Answer

We fix the level of significance as 0.05

Rule of p-value is,

p-value <=0.05 then reject Ho (Ho: null hypothesis)

If p-value >0.05 then accept Ho

Here based on the rule above we can make our conclusion,

p-value =0.05 so we can reject Ho

p-value =0.07 >0.05 so we will accept Ho

p-value = 0.01<0.05 here we will reject Ho

p-value =0.03<0.05 here also we will reject Ho
