Statistics have shown that a child 0 to 4 years of age has a 0.0002 probability of getting cancer in any given year. Assume that during each of the last seven years there have been 100 children ages 0 to 4 years whose parents work in a university’s business school. Four of these children have gotten cancer.

State your hypotheses and determine the appropriate p-value.
