A research hypothesis was thatstudents whose parents had attained a higher level of education would on average score higher on the SAT. The overall mean SAT math score was 514. SAT math scores for independentsamples of students follow. The first sample shows the SAT math test scores for students whose parents are college graduates with a bachelor's degree.

A professor believes that, in recent years, the ethnic composition of the students in the university has changed. According to the data collected a few years ago, there were 70% of students from European origins, 20% Asian origins, 5% Indigenous, and 5% Others. To test his belief, he randomly sampled 500 students and recorded their ethnicity as shown below: European 318 Asian 132 Indigenous 25 Others 25 The professor conducted a chi-squared goodness-of-fit test. Which of the following is the obtained chi-squared statistic for this test? A. 5.1443 B. 8.7898 C. 0.2288 D. 13.1657 E. 10.9777

Suppose a political science student wants to know whether gender is related in some way to Americans' views on environmental-protection standards. Since this student has an internship at the Environmental Protection Agency (EPA), he asks a simple random sample of 72 EPA employees whether they feel that current environmental regulations are adequate or inadequate. The student summarizes his data in a contingency table so that he can analyze it with a chi-square test for independence. Men Women Adequate 10 16 Inadequate 13 33 The requirements for a chi-square test for independence are not met because the sample is biased. at least one expected cell count is less than 1. either the row or column totals are not random. the categories overlap or do not contain all sample members. the observations are not independent.
