Matilde decides to test the accuracy of this serving size information. She plans to conduct a one-sample t-test with a significance level of = 0.01 to test the null hypothesis, Ho: = 225, against the alternative hypothesis, H 2.25, where is the average weight of a chip. Matilde selects a random sample of unbroken chips to weigh. She does not know the population standard deviation nor the distribution of chip weights, but she has confirmed that her sample does not contain any outliers. The summary statistics for her test are shown in the following table. Sample size Sample mean Sample standard deviation Test taistic Probability value rl p-value 0.093 2.22 0.13 Based on these results, complete the following sentences to state the decision and conclusion of the test. Matilde's decision is to the (p = 0.093). There is evidence to the claim that the average weight of is
