Answer:
Step-by-step explanation:
Given
4 % of the Population has genetic Mutation
Total Population [tex]n=910[/tex]
Probability of a mutant Person is [tex]p=0.04[/tex]
Since n> > p therefore we can write
mean [tex]\mu =np=910\times 0.04=36.4[/tex]
Standard deviation [tex]\sigma =\sqrt{np(1-p)}[/tex]
[tex]\sigma =\sqrt{910\times 0.04\times 0.96}[/tex]
[tex]\sigma =\sqrt{34.944}[/tex]
[tex]\sigma =5.91[/tex]
