Producer of Take-a-Bite, a snack food, claims that each package weighs 175 grams. Representative of the consumer advocate group selected the random sample of 70 packages. From this sample, mean is 172 grams. Population standard deviation is known to be 8 grams. Determine and interpret p-value for testing that mean weight of Take-a-Bite is less than 175 grams.
