Question

You have been screening compounds with the Ames test to determine if they are mutagenic. If a compound is mutagenic, more colonies will grow in the presence of the mutagen. You have obtained the following data from triplicate samples:
Number of mutant colonies
 Control: 55, 59, 61 Mean = 58.33333 SD= 3.05505
 Sample X: 52, 43, 42 Mean = 45.66667 SD= 5.507571
p - value = 0.025273
Question: Would you recommend that Sample X be included as a food additive? Why
(hint: What is the control for the Ames test?)
