Answer:
Standard deviation for the number of people with the genetic mutation = 4.178
Explanation:
Given random sample size 'n' = 600
proportion of the Population 'p' = 3% or 0.03
Let 'X' be the random variable in binomial distribution
Mean of the binomial distribution



Mean of the binomial distribution ' μ ' = 18
Standard deviation of the binomial distribution
Conclusion:
Standard deviation for the number of people with the genetic mutation = 4.178
