Consider the following partial analysis of variance table from a randomized block design with 6 blocks and 4 treatments. Test H0: there is no difference between treatment effects at A. Reject H0 B. Fail to Reject H0 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Randomized block design 1-1020 = .05. Chapter 01 - An Introduction to Business Statistics 96. Consider the following partial analysis of variance table from a randomized block design with 6 blocks and 4 treatments. Test H0: There is no difference between blocks at A. Reject H0 B. Fail to Reject H0 AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 3 Topic: Randomized block design 1-1021 = .05. Chapter 01 - An Introduction to Business Statistics 97. A researcher has used a one-way analysis of variance model to test whether the average starting salaries differ among the recent graduates from nursing, engineering, business and education disciplines. She has randomly selected four graduates from each of the four areas. If MSE = 4, and SSTO = 120 complete the following ANOVA table and determine the value of the F statistic. A. F = 8 B. F = 4 C. F = 6 D. F = 5 AACSB: Analytic Bloom's: Application Difficulty: Hard Learning Objective: 2 Topic: One-way ANOVA 1-1022 Chapter 01 - An Introduction to Business Statistics 98. A researcher has used a one-way analysis of variance model to test whether the average starting salaries differ among the recent graduates from nursing, engineering, business and education disciplines. She has randomly selected four graduates from each of the four areas. Determine degrees of freedom treatment, degrees of freedom error and degrees of freedom total and state the critical value of the F statistic at α = .05 A. 4, 12, 16, 3.26 B. 3, 12, 15, 3.49 C. 3, 12, 15, 3.24 D. 4, 12, 16, 3.01 DF (Treatment) = 3, DF (Error) = 12, DF (Total) = 15, F.05,3,12 = 3.49 AACSB: Analytic Bloom's: Application Difficulty: Hard Learning Objective: 2 Topic: One-way ANOVA 1-1023 Chapter 01 - An Introduction to Business Statistics 99. A researcher has used a one-way analysis of variance model to test whether the average starting salaries differ among the recent graduates from nursing, engineering, business and education disciplines. She has randomly selected four graduates from each of the four areas. If MSE = 4, and SSTO = 120 complete the following ANOVA table. Is there a significant difference in the starting salaries among the four disciplines? A. Reject H0 B. Fail to Reject H0 The starting salaries of recent graduates differ among the four disciplines. (F = 6) > F.05,3,12 = 3.49, therefore reject H0. AACSB: Analytic Bloom's: Application Difficulty: Medium Learning Objective: 2 Topic: One-way ANOVA 1-1024 Chapter 01 - An Introduction to Business Statistics 100. Suppose you are a researcher investigating the annual sales differences among five categories of businesses. Looking at a total of 55 companies equally divided among categories groups A, B, C, D, and E. Complete the following ANOVA Table and determine the value of the F Statistic A. 2.67 B. 7.50 C. 6.00 D. 5.88 AACSB: Analytic Bloom's: Application Difficulty: Hard Learning Objective: 2 Topic: One-way ANOVA 101. Suppose you are a researcher investigating the annual sales differences among five categories of businesses. Looking at a total of 55 companies equally divided among categories groups A, B, C, D, and E. Determine degrees of freedom treatment, degrees of freedom error and degrees of freedom total and state the critical value of the F statistic at = .05.
