9Choose orthogonal table
- Proposed standard methodchoose the first level
of factor A as a virtual level, - So we can choose L16(45)which has equal level and
just conduct 16 tests.

24- The best combination of apple juice is A3B4C4An
apple and a half, five teaspoons of sugar, four
tablespoons of vinegar.
25- The order of the significant factors is ABC,
which means the greatest impact on the taste of
the apple juice is the number of apples,
followed by sugar,and vinegar is the least

28- By analyzing the significance of each factor
level, considering the low-cost, easy to operate
and other factors, we get the best combination of
apple juice A3B4C1-- by means of analysis of
variance.
29- Error e1.3
- The personal preferences, for instance some
people prefer sweet, but some people prefer sour
30- Other factors that may affect the taste of the
apple juice that we do not know - Because of the existence of errors in personnel,
raw materials, environment, these can lead to
large errors in the final results

32Summary
- As an undergraduate, through this test, our
greatest achievement is not the results of the
experiment itself, but rather learn how to apply
the knowledge learned into practice.For
companies,adoping this method can both save cost
and meet the consumer demand.
