Today in class we learned the difference between uniform distribution: all the probabilities are the same, binomial experiment: has success or failure, binomial distribution: results of the experiment.
we went over how to find the binomial distribution.
1. [2nd] [vars] go to binompdf (0)
2. First number= trials [,] second number= probability of success on each trial [enter]
3. [sto->] [2nd] [2] to get L2 [stat] [enter]
4. [2nd] [y=] [enter] turn on the first graph, make sure you select a histogram graph, make frequency L2
5. [window] change window to what you need for that particular graph [graph]
** note : look over pages 98-102 and page 349 **
the following MUST BE TRUE to make it a binomial distribution:
1. The experiment consists of n identical trials
2. Each trial results in one of two outcomes: the outcomes are often called a "success" (S) and a failure (F)
3. Probability of a success on a single trial is equal to P and remains the same from trial to trial. The probability of a failure is Q=1-P
4. The trials are independent.
5. The random variable of interest is Y, the number of successes observed during n trials.
