A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 419 gram setting. It is believed that the machine is underfilling the bags. A 99 bag sample had a mean of 417 grams with a standard deviation of 25. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. State the null and alternative hypotheses. Assume the population distribution is approximately normal. State the null and alternative hypotheses.
