A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 450 gram setting. Based on a 12bag sample where the mean is 443grams and the standard deviation is 25, is there sufficient evidence at the 0.01 level that the bags are underfilled? Assume the population distribution is approximately normal. Find the value of the test statistic. Round your answer to three decimal places.
