Question

2. ANOVA Table (7 points) 2a. Study the following ANOVA summary table. Provide the missing information for the cells designated A to E. The cells that are blacked out do not need to be filled in. Attach your work on a separate sheet of paper. (5 points) SS IVS F. critical df 14 Source Between Within Total 125 30 2b. What is your statistical decision regarding Ho (p=0.05)? (2 points)

Answer 1

2a )

Source	SS	df	MS	F	F-critical
Between	550-125=425	14	$\frac{425}{14}=30.36$	$\frac{30.36}{15.625}=1.943$	3.237
Within	125	22-14=8	$\frac{125}{8}=15.625$
Total	550	22

F critical value = 3.237............by using F critical value table or by using Excel command =FINV(0.05,14,8)

2b) F test statistic = 1.943 < F critical value = 3.237

Therefore, we fail to reject H0 at  

0.05
