A researcher randomly selects a sample of 61 former student leaders from a list of graduates of UNCG who had participated in leadership positions while a student. She discovered that it has taken an average of 4.97 years for these student leader graduates to finish their degrees, with a standard deviation of 1.23. The average for the entire student body is 4.56 years. Is the difference between student leaders and the entire student population statistically significant at the alpha=.05 level? Hint: Follow the 5step method for hypothesis testing to see if it is significant. Make sure that you show the results of your t-tests and interpret your results in terms of the original research question. (Note the sample size, be sure to use the T distribution, Appendix C, rather than the Z distribution in Appendix B). 3.A researcher randomly selects a sample of 61 former student leaders from a list of graduatesof UNCG who had participated in leadership positions while a student.
