A restaurant advertises that its burritos weigh 250\text{ g}250 g250, start text, space, g, end text. A consumer advocacy group doubts this claim, and they obtain a random sample of 242424 of these burritos to test if the mean weight is significantly lower than 250\text{ g}250 g250, start text, space, g, end text. They calculate a sample mean weight of 242\text{ g}242 g242, start text, space, g, end text and a sample standard deviation of 12\text{ g}12 g12, start text, space, g, end text. The advocacy group wants to use these sample data to conduct a ttt test on the mean. Assume that all conditions for inference have been met. Identify the correct test statistic for their significance test
