The poll shows Obama had...

The poll shows Obama had only a statistically insignificant lead of 47% to 44% over Clinton, down sharply from a 14 point edge he held over her in February when he was riding the tide of 10 straight victories.

The March 13-14 poll surveyed 525 likely Democratic primary voters for the matchup between Clinton and Obama. It has a margin error of plus or minus 4.4 percentage points.Assignment: For this week’s exercise, you are to do an internet search and find an article discussing survey results for an election. It can be for any election in any state as long as the article reports the number surveyed and the margin or error. Once you find the article, do the following:

a) Verify the margin of error by doing you own calculation. Include the calculation in your post. It is okay if the margin of error in the article is off by 0.1 from what you get (roundoff error).

b) Report the confidence intervals for the top two candidates in the article. Do they overlap or not?

c) Discuss the headline or the opening sentence of the article as it relates to your answer for part b.

d) Include at the end of your post a link to the article.
