STUDENET HANDOUT STATWAY™ STUDENT HANDOUT  9 Lesson 10.1.2 Central Limit Theorem for Sample Means TAKE IT HOME 1 A possible population distribution is one that is triangular. Use the applet to construct a triangular population distribution. A What is the mean and standard deviation of your triangular population? != ! = B Use the Central Limit Theorem to calculate the mean and standard error of the sampling distribution when the sample size is n = 100. !! = != !! =
!
! = C Set the sample size, n, to 100 and set the number of samples, N, to 1000, and click Sample. What is the shape of the sampling distribution? D How close are the values from (B) to the mean and standard error of your sampling distribution? 2 Yet another possible population distribution is one that is bimodal. For example, suppose you took samples of the length of human hair in your school. It is probable (but not certain!) that young women tend to have long hair and young men have short hair. Use the applet to construct a bimodal population distribution.
