Independent random samples of voters from two voting districts, G and H, were selected to investigate the proportion of all voters who favor a proposal to widen a road that runs through both districts. The difference between the sample proportions (G minus H) was used to create the 95 percent confidence interval (0.13,0.47)
for the population difference between districts.
Which of the following is the best interpretation of the interval?
It is likely that the majority of voters in both districts favor the proposal, because all values in the interval are positive.
A
It is likely that more voters in district H favor the proposal than in district G, because all values in the interval are positive.
B
It is likely that more voters in district G favor the proposal than in district H, because all values in the interval are positive.
C
It is likely that less than half the voters in both districts favor the proposal, because all values in the interval are less than 0.5.
D
It is likely that there is no difference between the districts in voters who favor the proposal, because 0 is not contained in the interval.
