Show all important values you use as part of your test, including the null hypothesis, alternate hypothesis, test statistic value, and either the rejection region and critical value or p-value depending on the method you choose to use. State the result of your test in a complete sentence in context of the question. SECTION IICreate 90% confidence intervals for the average 4-year graduation rate for the VA schools in the top 100 public Universities in 2003 and the NC schools in the top 100. Using these confidence intervals, what would you conclude about your three research questions? Why? SECTION IIIDid you find a different results using the confidence intervals than when you used hypothesis tests? If so, why do you think the results were different? If not, which method is better to answering your question? Does one method give you better information than the other?

    You are to use the Top 100 public Colleges 2003 Data Set for this project. Data sets may be found in the "Data Set" module in Canvas. Virginia has six schools on this list, and North Carolina has 5. A researcher hypothesizes that the colleges in Virginia and North Carolina have high four-year graduation rates. This project addresses these hypothesis by asking the following questions: (1) Is the average 4-year graduation rate for the Virginia colleges in the top 100 public Universities greater than the average of all the top 100 public colleges, and (2) Is the average 4-year graduation rate for the North Carolina colleges in the top 100 public Universities greater than the average of all the top 100 public colleges? (3) Finally, the researcher is interested in the comparison between VA and NC schools. Is the average 4-year graduation rate different for the VA and NC schools?
