Hillary Shows Statistically Significant Improvement in Ohio

According to the latest Quinnipiac University Polls for Ohio, the poll numbers of Hillary Clinton have shown a statistically significant improvement during the past two months. A poll of 528 randomly selected registered Democrats in the state taken on August 31 shows her at 44%, whereas similar Quinnipiac polls taken on August 5 and July 6 show her at 41% and 35% respectively. The margin of error of each poll is 4.3%. This means that we are 95% certain that her August 31 approval among all registered Democrats in Ohio was between 39.7% and 48.3% and that we are also 95% confident that her July 6 approval was between 30.7% and 39.3%. Since these intervals do not overlap, we conclude that we are over 95% confident that her approval among all registered Republicans in Ohio is has increased from July 6 to August 31.
