This is an activity to explore the Negaive Binomial Probability Distribution.
- Description: You can access the applets for the above distributions at http://www.socr.ucla.edu/htmls/SOCR_Distributions.html .
- Exercise 1: Use SOCR to graph and print the following distributions and comment on the shape of each one of them:
- a. Failed to parse (unknown function\math): X <\math> follows negative binomial with <math> r=5, \ p=0.2 <\math>. ** b. <math> X <\math> follows negative binomial with <math> r=5, \ p=0.9 <\math>. ** c. <math> X <\math> follows negative binomial with <math> r=20, \ p=0.3 <\math>. ** d. <math> X <\math> follows negative binomial with <math> r=20, \ p=0.9 <\math>. * '''Exercise 2:''' Let <math> X <\math> follows the negative binomial distribution with <math> r=5, \ p=0.2 <\math>. Explain in words what <math> P(X > 10) <\math> means and use SOCR to compute this probability. Below you can see the distribution of <math> X \sim b(20,0.3) <\math> <center>[[Image: SOCR_Activities_Christou_negbinomial.jpg|600px]]</center> <hr> * SOCR Home page: http://www.socr.ucla.edu {{translate|pageName=http://wiki.stat.ucla.edu/socr/index.php?title=SOCR_EduMaterials_Activities_ConfidenceIntervals}}
