9) A bakery claims that the average weight of its cupcakes is 100 grams. You sample 30 cupcakes and find their weights as follows: [98, 99, 101, 102, 100, 99, 100, 101, 97, 98, 99, 100, 101, 102, 98, 100, 99, 98, 100, 99, 101, 100, 99, 100, 101, 102, 99, 98, 101, 100]. Can you conclude that the bakery's claim is accurate at a 5% significance level?
