MATH 302 Week 3 Discussion | American Public University System
Week
3 Forum / Topic: Probability and counting
rules; Discrete probability distributions
Topic:
Probability and counting rules; Discrete probability distributions
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
forum. 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
RealizeIT.
There are additional PDFs that were created to
help you with the Homework, Lessons and Tests in RealizeIT. While they
won't be used to answer the questions in the discussion forum, they are just as
useful and beneficial. I encourage you to review these ASAP! These
PDFs are also located at the bottom of the forum.
Instructions: Your initial post should be at least 150 words. You must
also respond to at least 2 other students. Responses should be a minimum
of 50 words and 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.
