The value of q is (Type an integer or a decimal.) Enter your answer in each of the answer boxes AE 20 p

Explanation / Answer

no of subjects that were given the placebo = 410

so sample size i.e n = 410

percent of subjects developed headaches = 13%

proability that subjects developed headaches i.e p = 0.13

q = proability that subjects didn't develop headaches

so q = 1-p = 1-0.13 = 0.87

parameters that would be used to find mean and standard deviation are n=410, p=0.13 and q = 0.87
