When the results of a survey or poll are published, the sample size and the margin of error should both be given

When the results of a survey or poll are published, the sample size and the margin of error should both be given. For example 1000 voters were surveyed and 39±2% of the voters agree with the president. In this example, N=1000 and the margin of error (MoE) is 2%.
This website lists several public opinion polls. Search the site and find a poll where the sample size and margin of error are given. Try to find a poll dealing with a topic in your profession or one in which you are really interested.
Main Post: Determine the following information for the selected poll results and include in your initial post. See Example and DB starter video in Unit 6 LiveBinder.
1. URL for the website. State the poll question, the sample size n, and the margin of error (also known as sampling error).
2. Interpret the results of your poll using your own words and full sentences. Note: Depending on the question asked, your poll may have more than one poll result – you only need to discuss one result.
3. State the confidence interval using the MoE. What does this confidence interval estimate?
4. Use the Confidence Interval template https://youtu.be/vHXLZ0RfU1E to calculate the confidence interval based on the sample size and the number of successes (the proportion you are interested in). Use a confidence level of 95%.
5. What is the calculated confidence interval? How does this compare to the interval in part 3 using the poll’s margin of error?
6. Discuss potential biases that could skew sampling results.

Hypothesis testing typically begins with a theory, a claim, or an assertion about a particular parameter (mean, μ, or proportion, p) of a population.
The Federal Trade Commission (FTC) is an independent agency of the U.S. federal government charged with preventing unfair or deceptive trade practices. It regulates advertising, marketing, and consumer credit practices, and also prevents antitrust agreements and other unfair practices.
The FTC publishes press releases regularly about health and fitness claims athttps://www.ftc.gov/news-events/media-resources/truth-advertising/health-claims
Main Post: Find a claim about a product or service from one of the press releases listed in the FTC website. Read through these and select one of interest to you that has not been picked by anyone else yet in class. See Example and DB starter video in https://youtu.be/R3AozFRuLWE
1) Summarize the advertising claim as shared in the media. What population parameter (mean, μ, or proportion, p) is the claim about?
2) If you were to formulate a hypothesis test about this product/service, what would your null and alternative hypothesis be? (Be sure to use all the correct notations for H0 and Ha)
3) State whether you have a one-tailed lower, one-tailed upper, or two-tailed test (Be sure you use the correct inequality signs).
