Answer:
a)5:2
b)14
c)17
Step-by-step explanation:
The ratio for babies to nursery workers is 5:2
To find the answer to b, we find how much you have to multiply 2 by to get 35, which is 7 and multiply that by the number of workers, 2, so you need 14 workers
To find the answer to c multiply 2 bye 3.5 to get 7 and multiply 5 by 3.5 to get 17.5 now rounf down so the answer to c is 17

The Normal approximation to the binomial
<span>is as follows
</span>
<span>mean=13(.5)=6.5 </span>
<span>variance=6.5(.5)=3.25 </span>
<span>Pr[fewer than 4]= </span>
<span>Pr[N<=3] Apply the continuity correction </span>
<span>Pr[N<=3.5]~=Pr[Z<3.5-6.5/sqrt(3.25)]=
</span>
<span>Pr[Z<-1.66]=0.048457226
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
