Question 907802: Use a normal approximation to find the probabilty of the indicated number of voters. In this case assume that 127 eligable voters ages 18-24 are randomly selected. Suppose a previous study showed that among eligable voters aged 18-24, 22% of them voted
probabilty that few than 34 voted?
The probabilty that fewer than 34 of the 127 eliable voted is ?

34/127 = .2677
P(x < 34) = p(z < %28.2677-.22%29%2Fsqrt%28%28.2677%29%28.7323%29%2F127%29)
