A manufacture makes light-weight sneakers, and claim that the average weight of one sneaker is no bigger than 2 pounds. To verify this claim, a sample of 9 sneakers are weighed, and the sample mean is 2.4 pounds with the sample variance of 0.25 pounds 2. Assuming the weights of sneakers are normally distributed, we would like to test the claim of the manufacture at 10% level of significance. Please select the correct statement from below: O None of the other answers The null hypothesis HO is p > 2 pounds. Since p-value > 0.10, HO is accepted and the manufacture's claim is true, The null hypothesis HO is u s 2 pounds. Since p-value > 0.10, HO is accepted and the manufacture's claim is true, The null hypothesis HO is p > 2 pounds. Since p-value < 0.10, HO is rejected and the manufacture's claim is true. The alternative hypothesis H1 is p > 2 pounds. Since p-value <0.10, HO is rejected and the manufacture's claim is false.
