Answer:
at 0.05 level of significance there is no way or evidence to say for certain that the net weight will be greater than 28.7. because at 0.05 the mean will be equal to 28.7 but because net weight is being assumed it is not actual weight there may be a possibility of the net weight to be greater than 28.7 but we cannot say for certain hence since there is no evidence then we cannot conclude.
