Please fill in table and answer both questions
a) In the table, is the factor sifnificant at the 5% level?
b) how many observations are there?
| source | ss | df | ms | f |
| treatment | ? | 2 | 24.9 | ? |
| error | 22.9 | ? | ? | |
| total | ? | 29 |
Solution
Source
SS
Df
MS
F
Treatment
2*24.9= 49.8
2
24.9
24.9/0.8481 = 29.3581
Error
22.9
27 ( 29-2)
22.9/27= 0.8481
Total
49.8+22.9 = 72.7
29
Table value of F with DF 2 and 27= 3.35
Calculated F=29.3581 > 3.35 table value
Reject the null hypothesis.
The factor significant at the 5% level
Number of observations = total DF +1 = 29+1 = 30
| Source | SS | Df | MS | F |
| Treatment | 2*24.9= 49.8 | 2 | 24.9 | 24.9/0.8481 = 29.3581 |
| Error | 22.9 | 27 ( 29-2) | 22.9/27= 0.8481 | |
| Total | 49.8+22.9 = 72.7 | 29 |
