Antioxidants
A food processor wants to compare two antioxidants for their effects on retarding spoilage.Suppose 16 cuts of fresh meat are treated with antioxidant A and 16 are treated with antioxidant B,and the number of hours until spoilage begins is recorded for each of the 32 cuts of meat.The results are summarized in the table below 
-{Antioxidants Narrative} State the null and alternative hypotheses for determining if the population variances differ for Antioxidants A and B.
Definitions:
Null Hypothesis
The null hypothesis is a statement or hypothesis that there is no significant difference or effect, typically to be tested against an alternative hypothesis.
Critical Value
The threshold in a statistical test such that if the calculated test statistic is beyond this point, the null hypothesis is rejected.
Chi-Square Tests
Statistical tests used to determine if there is a significant difference between the expected frequencies and the observed frequencies in one or more categories.
Test Statistic
A value calculated from sample data used to evaluate the credibility of a hypothesis about a population.
