A human resource manager is interested in whether absences occur during the week with equal frequency. The manager took a random sample of 100 absences and created the following table: Calculate the expected absences for all 5 days. A. 28 B. 20 C. 12 D. 25 100/5 = 20 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 1 Topic: Chi-Square 1-1128 Chapter 01 - An Introduction to Business Statistics 85. A human resource manager is interested in whether absences occur during the week with equal frequency. The manager took a random sample of 100 absences and created the following table: Calculate the value of the chi-square statistic. A. 6.80 B. 9.49 C. 27.2 D. 1.36 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 1 Topic: Chi-Square 1-1129 Chapter 01 - An Introduction to Business Statistics 86. A human resource manager is interested in whether absences occur during the week with equal frequency. The manager took a random sample of 100 absences and created the following table: How many degrees of freedom are associated with the chi-square test? Use α = .05 and determine the rejection point condition of the chi-square statistic. A. 5, 9.49 B. 5, 6.80 C. 4, 9.49 D. 4, 6.80 d.f. = 5 - 1 = 4 χ2.05,4 = 9.488 AACSB: Analytic Bloom's: Application Difficulty: Easy Learning Objective: 1 Topic: Chi-Square 1-1130 Chapter 01 - An Introduction to Business Statistics 87. A human resource manager is interested in whether absences occur during the week with equal frequency. The manager took a random sample of 100 absences and created the following table: At a significance level of .05, test Ho: the probabilities are equal for all five days. A. Reject H0 B. Fail to reject H0 χ2 = 6.80 < 9.488, fail to reject Ho AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 1 Topic: Chi-Square 1-1131 Chapter 01 - An Introduction to Business Statistics 88. At a recent meeting of educational researchers, comparisons were made between the type of college freshmen attend and the numbers who drop out. A random sample of freshmen shows the following results: Determine the expected frequencies for the two cells of 4-yr public institutions that will be used in the chi-square test of independence. A. 10.9, 25.1 B. 10.0, 26.0 C. 18.0, 18.0 D. 39.4, 102.6 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Chi-Square 1-1132 Chapter 01 - An Introduction to Business Statistics 89. At a recent meeting of educational researchers, comparisons were made between the type of college freshmen attend and the numbers who drop out. A random sample of freshmen shows the following results: Determine the expected frequencies for the freshmen who drop out of 2-year institutions that will be used in the chi-square test of independence. A. 15.0, 9.0 B. 10.0, 10.9 C. 18.0, 18.0 D. 11.7, 92.6 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Chi-Square 1-1133 Chapter 01 - An Introduction to Business Statistics 90. At a recent meeting of educational researchers, comparisons were made between the type of college freshmen attend and the numbers who drop out. A random sample of freshmen shows the following results: At a significance level of .05, determine the appropriate degrees of freedom and the rejection point condition for this test. A. 6, 4.80 B. 7, 14.1 C. 4, 9.49 D. 3, 7.81 (r-1) (c-1) = (2-1) (4-1) = 3 degrees of freedom χ2.05,3 = 7.815 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Chi-Square 1-1134 Chapter 01 - An Introduction to Business Statistics 91. At a recent meeting of educational researchers, comparisons were made between the type of college freshmen attend and the numbers who drop out. A random sample of freshmen shows the following results: Calculate the chi-square statistic for this test of independence. A. 7.81 B. 4.80 C. 2.50 D. 6.67 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Chi-Square 1-1135 Chapter 01 - An Introduction to Business Statistics 92. At a recent meeting of educational researchers, comparisons were made between the type of college freshmen attend and the numbers who drop out. A random sample of freshmen shows the following results: Use a significance level of .05 and determine if the type of school and the drop rate are independent (null hypothesis is that dropout rate is independent of type of school) A. Reject H0 B. Fail to reject H0 Ho: Dropout rate is independent of type of school Ha: Dropout rate and type of school are dependent χ2 = 4.8046 χ2.05,3 = 7.815 Reject Ho if χ2 > χ2.05,3 failed to reject AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Chi-Square 1-1136 Chapter 01 - An Introduction to Business Statistics 93.
