Question

1. Look at the ANOVA source table that has a large portion of the information blanked out. Make the appropriate calculations, present a completed ANOVA table, and determine whether the results are statistically significant. You will need to find all values depicted as XXX in the table. (10 Points).

Source table

Source	Sum of Squares	df	Mean Square	F
Between	25.64	2	XXX	XXX
Within	XXX	XXX	2.28
Total	XXX	30

Answer 1

One way Anova table.

Source	Sum of squares	df	Mean square	F
Between	25.64	2
Within	28*2.28=63.84	30-2=28	2.28
Total	25.64+63.84=89.48	30

F test statistic value is 5.62

F critical value is =3.34.................................by using Excel command =FINV(0.05,2,28) or by suing F critical value table.

F test statistic value 5.62 > F critical value 3.34

Therefore, we reject H0 at

From the above anova table we can say that ,the results are statistically significant.
