A coin mint has a specification that a particular coin has a mean weight of 2.5g. A sample of 32 coins was collected. Those coins have a mean weight of 2.49522g and a standard deviation of 0.01571g. Use a 0.05 significance level to test the claim that this sample is from a population with a mean weight equal to 2.5g. What is the test statistic and what is the p-value? State the final conclusion.
