ANSWER
From given the data it is clearly understood that the naull hypothesis is accepted as,
from f value calculated we find it at 1.313. but the tabulated value of it stands to 3.07
so calculated value is less. so we can accept the null hypothesis.
Another explanation by alpha=0.05 value.
logic is as follows if significant values is greater than or equal to alpha value given then we can say the null hypothesis may be accepted with (1-alpha) % of confidence interval.
