p' = 29/122
p0 = 22% = 0.22
n = 122
we have,
z = (p'-p0)/sqrt(p0*(1-p0)/n)
z = (29/122 - 0.22)/sqrt(0.22*0.78/122)
z = 0.472
If we don't round off z score to 2 decimals, required probability = P(z <= 0.472) = 0.6815
If we round off z score to 2 decimals, required probability = P(z <= 0.47) = 0.6808
Giving 2 answers please input both to check the valid one (based on rounding in z score)

Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 110 eligible voters aged 18-24 are randomly selected Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 27 voted The probability that fewer than 27 of 110 eligible voters voted is Round to four decimal places as needed.)
