05 Dec Recall the car data set you identified in Week 2.

Recall the car data set you identified in Week 2.  You will want to calculate the average for your data set.  (Be sure you use the numbers without the supercar outlier)  Once you have the average count how many of your data points fall below the average. You will take that number and divide it by 10.  This will be your p or “success” in your problem.  Once you have p, calculate q.

If you were to find another random sample of 10 cars based on the same data, what is the probability that exactly 4 of them will fall below the average?  Make sure you interpret your results.

If you were to find another random sample of 10 cars based on the same data, what is the probability that fewer than 5 of them will fall below the average?  Make sure you interpret your results.

If you were to find another random sample of 10 cars based on the same data, what is the probability that more than 6 of them will fall below the average?  Make sure you interpret your results.

If you were to find another random sample of 10 cars based on the same data, what is the probability that at least 4 of them will fall below the average?  Make sure you interpret your results.

I encourage you to review the Week 3 Binomial probabilities PDF at the bottom of the discussion.  This will give you a step by step example to follow and show you how to find probabilities using Excel.  You can also use this PDF in the Quizzes section.

There are additional PDFs that were created to help you with the Homework, Lessons and Tests in the Quizzes section.  While they won’t be used to answer the questions in the discussion, they are just as useful and beneficial.  I encourage you to review these ASAP!  These PDFs are also located at the bottom of the discussion.

“Before you post your initial discussion, you must submit it in the assignment area in a Word file, so its originality can be checked by Turnitin.com. I will take points off if you do not do this. Your score will appear in the same place you submit your file. It can take up to 24 hours for a score to return, but usually, it is less than 30 minutes. Before you post your discussion in the activity, make sure your originality index (%) is less than 15. If it is greater than 15%, rewrite your discussion, submit it again in the assignment area and check the %. Keep doing this until your % is less than 15%. Only post your discussion when the % is less than 15. Here are two hints to get your score below 15%: 1) leave your list of supporting material out of the file you submit for checking (don’t forget to add these back when you post your discussion in the forum) and 2) use your own words, not quotes.

Once you have posted your initial discussion, you must reply to at least two other learner’s post. Each post must be a different topic. So, you will have your initial post from one topic, your first follow-up post from a different topic, and your second follow-up post from one of the other topics. Of course, you are more than welcome to respond to more than two learners.”

Instructions: You must respond to at least 2 other students. Responses may include direct questions. In your peer posts, compare the probabilities that you found with those of your classmates. Were they higher/lower and why? In your responses, refer to the specific data from your classmates’ posts.  Make sure you include your data set in your initial post as well.
