A manufacturer of chocolate chips would like to know whether its bag falling machine works correctly at the 401 gram setting, It is believed that the machine is underfing the bags. A 8 bag sample had a mean of 394 grams with a standard deviation of 12 . Assume the population is normally distributed. Is there sulficient evidence at the 0.85 level that the bags are underfilled? Step 5 of 6 : Identify the level of significance for the hypothesis test.

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 431 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 421 grams with a standard deviation of 20. A level of significance of 0.01 will be used. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the bags are underfilled
