oducts online. The shipping department manager claims that the average order shipped by their company is 1.89kgs. The general manager wants to verify if his claim is true. So, he randomly selects 25 samples of orders. What can the general manager conclude at 0.01 level of significance if the sample has a mean weight of 2.07kgs with a standard deviation of 0.72kg? What is your basis in rejecting the null hypothesis? What conclusion can you derive if you reject the null hypothesis? If you fail to reject the null hypothesis, does it mean that there is no enough evidence
