The use of preservatives by food processors has become a controversial issue Suppose two preservatives are extensively tested and determined safe for use in meats. A processor wants to compare the preservatives for their effects on retarding spoilage. Suppose 16 cuts of fresh meat are treated with preservative I and 16 are treated with preservative II, 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. 4 Preservative I Preservative II X-96 54 hours 51-18.8 hours X106.4 hours 5-10.1 hours Suppose ax = 0.01. Which of the following represents the result of the relevant hypothesis test? 1) The null hypothesis is not rejected. 2) The null hypothesis is rejected. 3) The alternative hypothesis is rejected. 4) Insufficient information exists on which to make a decision.
