------------
p = According to a National data it was found that 55% of male students live at home. In a random sample of 200 students conducted in a college, what is the probability that the survey will result that at least 130 students are living at home.
p = 0.55; n= 200
P(x>=130) = 1-binomcdf(200,0.55,129) = 0.00259
Comment: answer gotten using TI binomcdf function.
