well..the end of our statistic unit...this unit is also pretty hard....but i'm just pushing myself to get every details...i know right about now it's too late to ask for help to do the binomial distribution...i will try my best in this test...it's fun doing the confidence interval for me..calculating the mean and the standard deviation. To get the standardized. Well might as well tell myself goodluck for this test.
