Answer to Question #136138 in General Chemistry for Nash Gover

Question

A quality control lab measured the % moisture in four samples of raw hamburger
and got the following values: 64.53, 64.45, 65.10 and 64.78. An independent lab
with high-level analytical equipment obtained an average of 65.05% moisture.
In comparing the results of these two labs, choose the statement (s) you agree with:
(a) The difference in the two average values (for the results of the two labs) is less
than 0.05% moistures.
(b) The quality control lab is expected to have a higher level of accuracy than the
other lab.
(c) The quality control lab results seem to give a lower value overall (with one or two
exceptions);i.e., the data may have a systematic error which results in a lower
value than expected.
(d) None of these statements are reasonable.

Answer 1

(c) The quality control lab results seem to give a lower value overall (with one or two

exceptions);i.e., the data may have a systematic error which results in a lower

value than expected.
