hey everybody its icy today here..
today we were learning how to find the mean and standard deviation of a binomial distribution which looks like this
n*p=m binomial distribution
in stead of going threw the whole binompdf on the graphing calculator you can simply find the n which stands for number of trails the p which is the probability of success once you have found be you can find q which is q=1-p in order to find the strandard deviation you just plug in the numbers to this formula
squareroute of npq
so it would look like this in an example
squareroute (300)(.028)(.972) and that willl give you your stand deviation
to find the mean of abinomial distribution you find n and p and multiply them
we were assigned to do page 108 questions 1-6,8 from our text books for work plus a couple of worksheets to get a better understanding of all of this
