Question: A snack food company claims it packages 454 grams of pretzels per bag using a machine. A sample of 25 bags of pretzels were weighed with a mean of 450g. Assume the weights of the bags of pretzels are normally distributed with a standard deviation of 7.8. At the 5% significance level do the data suggest that the weights of the bags of pretzels are not equal to 454 grams? Conduct a hypothesis test using critical values with the template below to answer this question.
