A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 419419 gram setting. It is believed that the machine is underfilling the bags. A 99 bag sample had a mean of 417417 grams with a standard deviation of 2525. A level of significance of 0.0250.025 will be used. Assume the population distribution is approximately normal. State the null and alternative hypotheses.
