A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 408
gram setting. Based on a 23
bag sample where the mean is 416
grams and the variance is 784
, is there sufficient evidence at the 0.05
level that the bags are underfilled or overfilled? Assume the population distribution is approximately normal.

Step 1 of 5: State the null and alternative hypotheses.
