Find an article of your choice which uses proportions, and copy and paste the address of that article in this step. Identify at least one sample proportion within the article (you can list more than one if you like), and state what that sample proportion measures. For example, if you're told that the sample proportion of people in Renton who are taller than 5'11" is 80.7%, and you're also told that the sample size is 57, then you would state the proportion as 46/57 in your response for this part of the assignment. You will probably have to interpret what is being said in the article in order to be able to state specifically what the sample proportion represents. Also, you might not have x or n, you might only have the percentage or a decimal equivalent. Often, the size of the sample is stated somewhere in the article, and it's important to find that value. So, if n is given, please include it in this part of the assignment. If stated in the article, identify whether the sample is a random sample, or say that it wasn't stated. If stated in the article, please identify how the sample was created, or say that it wasn't stated. If you are told that, in general, 55% of all mice exhibit a particular behavior, and you take a random sample of 100 mice and discover that this particular behavior occurs in 78% of your sample, then which of the following is more likely to be true (select a or b, and explain why): The mice you've selected are, by chance, different from most mice. The given percentage of 55% is not correct. If you know for certain, that the behavior referred to in the previous question is, in fact, 55%, and if you have a random sample that gives you a proportion of 78%, then what possibly could account for getting a random sample of 78%? If your sample wasn't random, what might account for getting a sample proportion of 78%?
