Unformatted text preview: a significant difference in the annual sales of the five company categories at
05?
A. Reject H0
B. Fail to Reject H0
F = 7.5 > F.05,4,50 = 2.57, therefore reject Ho and annual sales differ among five company
categories. AACSB: Analytic

Topic: Oneway ANOVA 11026 =. Chapter 01  An Introduction to Business Statistics 103. A company that fills gallon containers of water has four machines. The quality control
manager needs to determine whether the average fill for these machines is the same. Looking
at 19 gallon containers we have the following data of fill measures in quarts: and the following partial ANOVA table: Complete the ANOVA table and calculate F.

Topic: Oneway ANOVA 11027 Chapter 01  An Introduction to Business Statistics 104. A company that fills gallon containers of water has four machines. The quality control
manager needs to determine whether the average fill for these machines is the same. Looking
at 19 gallon containers we have the following data of fill measures in quarts: and the following partial ANOVA table: Determine the degrees of freedom for the treatment, error, and total and state the critical value
of the F statistic at
= .05.
A. 4, 15, 19, 3.06
B. 4, 14, 18, 3.11
C. 3, 15, 18, 3.29
