Experiment d is repeated 35 times. Write an integral that estimates the probability that there is an average of less than 1.8 mutants per experiment 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
