you have read about hypothesis tes and will now apply this knowledge by writing a pp that addresses the following:
- Provide an example of a hypothesis where a one-tailed hypothesis test would be used.
- Provide an example of a hypothesis where a two-tailed hypothesis test would be used.
- If a researcher has set alpha at 0.05 for a two-tailed hypothesis test, what is the p-value required to reject the null hypothesis?
- A researcher has set alpha at 0.05. When the researcher analyzes the data from the experiment using a software program, she obtains a p-value equal to 0.932. Based on this p-value, should the researcher reject the null hypothesis or fail to reject the null hypothesis? Please explain your ans.
- A researcher has set alpha at 0.01. When the researcher analyzes the data from the experiment using a software program, he obtains a p-value equal to 0.04. Based on this p-value, should the researcher reject the null hypothesis or fail to reject the null hypothesis? Please explain your answ
- A researcher is interested in whether music played during an exa will improve exa performance. Students in one class listen to music during an exm and students in another class take the exm in silence. The researcher set alpha at 0.05. Test scores for both classes are compared using a statistical software program. The mean test score for the class that listened to music during the exm is 95, while the mean test score for the class that took the exa in silence is 82. The obtained p-value from the independent groups t-test is 0.02. Be sure to answer the following questions:
- State the null and alternative hypothesis.
- Determine if this is a directional or non-directional tes. Please explain your ans.
- Establish the conclusion of this study based on the p-value and the means provided.
- Describe the Type I error for this study.
- Describe the Type II error for this study.
