A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the425 gram setting. It is believed that the machine is underfilling the bags. A10 bag sample had a mean of419 grams with a variance of169. A level of significance of0.1 will be used. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the bags are underfilled? Is it there is not sufficient evidence to support the claim that the bags are undefiled or there is sufficient evidence to support the claim that the bags are underfilled?
