A quality control inspector
measures the masses of boxes of
raisins. He wants to know if the
average mass of a box of raisins is
100 g. The inspector randomly
chooses boxes of raisins.
The masses, in grams, are:
99.1, 101.7, 99.8, 98.9, 100.8, 100.3,
98.3, 100.0, 97.8, 97.6, 98.5, 101.7,
100.2, 100.2, 99.4, 100.3, 98.8, 102.0,
100.3, 98.0, 99.4, 99.0, 98.1, 101.8,
99.8, 101.3, 100.5, 100.7, 98.7, 100.3,
99.3, 102.5

a) For the shipment to be approved,
the average mass of a box of
raisins must be at least 100 g.
Which average could someone
use to describe this shipment to
get it approved? Explain.

I am actually not sure what the question is asking.  It is badly worded.

I assume you are meant to be finding the average.  Have you done that yet?

Exactly what is wanted could perhaps be surmised by what you have been learning.  What have you been learning?
