A candidate for one of Ohio's two U.S. Senate seats wishes to compare her support among registered voters in the northern half of the state with her support among registered voters in the southern half of the state. A random sample of 2000 registered voters in the northern half of the state is selected, of which 1062 support the candidate. Additionally, a random sample of 2000 registered voters in the southern half of the state is selected, of which 900 support the candidate. The estimate (again, using the large-sample estimate) for the proportion of registered adults in the southern half of the state who support this candidate is
a. 0.183
b. 0.450
c.0.375
d.0.825
Answer:
Given,
sample n = 2000
x = 900
sample proportion p^ = x/n
= 900/2000
= 0.450
So Option B is right answer.
