Answer #1

Ans:

Sampling distribution of sample proportions:

Given that

population proportion,p=0.7

n=225

mean=0.7

standard deviation=sqrt(0.7*(1-0.7)/225)=0.0306

a)sample proportion=0.6

z=(0.6-0.7)/0.0306=-3.27

P(z<-3.27)=0.001

b)sample proportion=0.78

z=(0.78-0.7)/0.0306=2.62

P(z>2.62)=0.004
