A quality control technician at a coin mint wants to test a claim that a particular coin has a mean weight of 2.5 grams. A random sample of 32 coins was collected. Those coins have a mean weight of 2.49537 grams and a standard deviation of 0.01145 grams. At a = 0.05, can you reject the coin mint's claim? Assume the population is normally distributed. Interpret the decision in the context of the original claim. Choose the correct answers below. At the 5% level of significance, there [ Select] is/is not enough evidence to [ Select] support/reject the claim that a particular coin has a mean weight of 2.5 grams.
