To determine if there is a relationship between grade performance and extracurricular participation, North Carolina State conducted a study of 112 students, recording the number of students in each of three extracurricular categories, and each of two grade categories. Here are the results:Source: Felder, et al., "A Study of Student Performance in an Introductory Chemical Engineering Course," 1992 ASEE Annual Conference Proceedings, pp. 1516–1519.Which one of the following facts should make you the most worried about the reliability of the results of the test in this case? Two of the observed counts are less than 5. The 112 students were all students in a chemical engineering course and not a random sample from the entire student body. Not all of the cells' contributions to the chi-squared statistic are greater than 1. Two of the six expected counts are less than 5.

Here are the results:Source: Felder, et al., "A Study of Student Performance in an Introductory Chemical Engineering Course," 1992 ASEE Annual Conference Proceedings, pp. 1516–1519.The expected count of students with high extracurricular participation and good grades is the number of students that you would expect to see assuming that which of the following is correct? Check all that apply. The conditions that allow us to safely use the chi-squared procedure are met. Extracurricular participation and grade performance are related. Extracurricular participation and grade performance are independent. The null hypothesis of the chi-squared test for independence in this case is true.Question 6Select one answer.10 pointsIn a 2012 report from the U.S. Department of Education breaking down the race and gender of every U.S. college graduate receiving a bachelor's degree in 2009–2010, we see the following data for white, black, and Hispanic graduates.
