some students checked 6 random bags of doritos marked with net weight of 28.7 grams. is their evidence showing mean net weight is higher that 28.7. 0.05 significance level

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.

Step-by-step explanation:

Net weight: this is the actual weight of a product without the weight of the container or sack it is being stored in.
