A manufacturer of chocolate chips would
like to know whether its bag filling machine
works correctly at the 419.0419.0 gram
setting. It is believed that the machine is
underfilling the bags. A 3838 bag sample
had a mean of 409.0409.0 grams. A level
of significance of 0.050.05 will be
used. State the hypotheses. Assume the
standard deviation is known
to be 22.022.0.
