In this study, the college instructor aims to know whether there are differences in the performance of students among the three classroom environments. We consider the . as the factor variable. Also, the response variable is the which is in the . level of measurement. The students were independently and randomly assigned to each of the three classroom environments: Mozart piece, relaxation music, and silence. The p-values obtained from the Shapiro-Wilk test indicate that the assumption of . was Further, results obtained from the Levene’s test indicate that the assumption of was Considering the variable of interest and the results of the test for the assumptions, the appropriate test procedure to analyze the given data is the The test yielded a p-value equal to Click or tap here to enter text..

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.
