Question 1055025
 5% of the patients using a high blood pressure drug will experience side effects {{{p= .05}}}

sample mean: p =15/250 = .06
P(p <= .06) = P( z<= {{{blue (x - mu)/sqrt(blue(p(1-p)/n))}}})

{{{z =blue (.06 - .05)/sqrt(blue((.05*.95)/250))}}} = .725476
P(z <= .725476) = normalcdf(-100, .7255) =  .7659
