Explanation / Answer

Ans:

a)Option B is correct.

b)pooled proportion=(0.55*500+0.44*500)/1000=0.495

Test statistic:

z=(0.55-0.44)/sqrt(0.495*(1-0.495)*((1/500)+(1/500)))

z=3.48

c)alpha=0.1

critical z value=1.28

d)p-value=P(z>3.48)=0.0003

e)Option C is correct(As p-value is less than alpha,so there is sufficient evidence to reject H0)
