Question

A researcher designs an experiment using two drugs, she prepares 15 independent flasks of yeast growth medium and yeast cells. She adds tunicamycin (T) or caffeine (C) to 5 flasks each. Remaining 5 flasks get no drugs (ND). Doubling time of the yeast cells are measured in each flask, data is provided below:

Flask	T	Flask	C	Flask	ND
1	8.2	6	5.2	11	6
2	6.8	7	6.1	12	5.1
3	8	8	6.2	13	5.6
4	7.6	9	5.7	14	5.2
5	7.9	10	6.3	15	6.1

a. Test if mean doubling time is different in Caffeine (C ) when compared to no drug (ND) using an ANOVA method, report an approximate p-value for the level of significance.

b. If a drug decreases the doubling time of yeast cells, what could be the purpose of using this drug?
