- 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.

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…PLEASE ANSWER ALL THE PARTS OF THE QUESTION ( THIS IS NOT A GRADED ASSIGNMENT)A survey found that about 49% of the people who work at an accounting firm take a company car pool van to work. a.
