You plan on exposing 9 strains of bacteria (labelled A - I) to amutagen. You hypothesize that mutagen A induces more mutations thanmutagen B. Following each exposure, you count the mutationsobserved in the genome compare to the wild strain genotype. Figureout what kind of statistical test would be appropriate for thisstudy.
Number mutations observed in genome
Mutation   A B   C   D E  F   G H I
Mutagen A 52 17 45 40 20 30 10 Â Â 15 Â Â 41
Mutagen B 59 15 63 40 17 45 32 20 40
What is your null and alternate hypothesis?  What areyour statistical results?  Should you reject, or fail toreject, your null hypothesis? Why?
