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…
