Create a research hypothesis in your area of study that would be answered using either an independent or dependent samples t test.
Include the following:
1. Introduction: Brief description of the study including the purpose and importance of the research question being asked.
2. What is the null hypothesis? What is the research hypothesis?
3. Participants/Sampling Method: Describe your sampling method. What is your sample size? Who is your population of interest? How representative is the sample of the population under study?
4. Data Analysis: Describe the statistical analysis. (HINT: This should either be an independent or dependent samples t test depending on your research question). What is your IV? What is your DV? What level of measurement are your IV and DV? What is your alpha level?
5. Results & Discussion: Did you reject the null hypothesis? What information did you use to lead you to your conclusion? Was your p value greater than or less than your alpha? NOTE: You can just make up numbers, but include your made-up p value.
Determining probability when guessing answers. Test comprise of multiple- choice questions each having 4 possible answers (a, b, c, d) one of which is right. Suppose that you guess answers to six such questions.
An airline tracks data on its flight arrivals. Over the past six months, 65 flights on one route arrived early, 273 arrived on time, 218 were late, and 44 were cancelled.
Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some situations in which you might accept a higher level (e.g., 0.1)?
Calculated test statistic, decision about the null hypothesis interpretation of results, and a list of references consulted.
If there is enough evidence to reject the claim of no difference in the ages of the two groups. Use the standard deviations from the samples and the P-value method.

A random sample of 64 light bulbs indicates a sample mean life of 350 hours. At the 0.05 level of significance, is there evidence that the mean life is different from 375 hours?
If 350 respondents out of a random sample of 1,000 Americans reported that they did not trust their government, what is your estimation at a 99% confidence level of the proportion of the American population who do not trust their government?
