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) Calculate the mean, median, and

mode masses.

b) 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.
