Experiment b is repeated 80 times. Write an integral that estimates the probability that there are between 30 and 40 mutants, and shade the corresponding area on a sketch of the approximate normal p.d.f. Take a guess at the probability based on your sketch.
Recall the data describing the probabilities of the outcomes of four experiments counting the number of mutants in a bacterial culture.

Suppose that each experiment is repeated (independently) and the total number of mutants is counted.

Probability Number Experiment Experiment Experiment Experiment of Mutants 0.1 0.2 0.3 0.3 0.1 0.6 0.3 0.1 0.0 0.0 0.3 0.2 0.2 0.2 0.1 0.1 0.3 0.1 0.4 0.1
