(Required) Create and post a response that fully answers one of the 10 questions below (no later than Wednesday)
(Required) Create and post a response that fully answers a different one of the 10 questions below (on a different day)
(Required) Post one quality response to another classmates’ “main” post or to a professor post (by the end of the week).
(Required) The posts must be submitted on at least 3 different days.
(Optional) Additional posts and/or days of participation are not required, but are certainly welcome!
NOTE: Always paste the question itself (and its number) above your answer (or enough of it, when it’s a really long question, to make it clear which one you are addressing).
For full posting guidelines, review the Real World Discussions: Requirements page.
1. Show the calculation…
1. Show the calculation to find the μ and σ of a binomial variable whose probability of success if 0.3 with a total number of attempts of 20.
2. Probability of Success…
2. Show the calculation to find the μ and σ of a binomial variable whose probability of success if 0.7 with a total number of attempts of 40.
3. Different Probabilities of Success
3. Show the calculation to find the μ and σ of a binomial variable with a total number of attempts of 30 with first with the probability of success of 0.2 and then again with the probability of success of 0.8. Compare and discuss the differences.
4. Graph Distribution 1
4. Graph the entire distribution of a binomial variable whose probability of success if 0.3 with a total number of attempts of 20.
5. Graph Distribution 2
5. Graph the entire distribution of a binomial variable whose probability of success if 0.7 with a total number of attempts of 40.
6. Eat 2 M&Ms
6. There are 10 M&Ms of which 6 are green, in a bowl. You select 2 of them and eat each after it is selected. Is this a binomial experiment? Why or why not?
7. Put the M&Ms Back!
7. There are 10 M&Ms of which 6 are green, in a bowl. You select 2 of them and putting each back in the bowl after it is selected. Is this a binomial experiment? Why or why not?
8. Binomial Experiment Situation
8. Describe a situation that would result in a binomial experiment. Relate to each part of that situation to the definition of a binomial experiment.
9. Solve Binomial Probability
9. Use the binomial experiment that a peer described in their response question #8. From that, create and solve a binomial probability. You may need to make a few assumptions, which is fine.
10. Ethics! (Be honest)
10. Ethics: Describe a situation where using a binomial probability with only two outcomes would be misleading. What would make that use misleading and how might it be presented more effectively (honestly)?
